2. Creative Core

Unwarranted Trail is not simply a film about hunting down a serial killer.

What it truly addresses is this:

How an outwardly ordinary, gentle, normal man gradually converts "love" into possession in each intimate relationship, interprets "breaking up" as betrayal, and—each time a relationship ends—makes the other person vanish from the world.

The film does not portray the killer as a genius psychopath, nor does it reduce him to a purely cold-blooded villain.
He does not plan to kill from the very beginning every time.
But when a relationship reaches its point of no return—when the other person truly wants to leave—he repeatedly crosses the same irreversible line.

He was afraid once.
He regretted once.
He even returned to old places, as if in remembrance, confirmation, atonement.
But after escaping institutional scrutiny again and again, those guilt pangs slowly curdled into a different kind of arrogance.

Until the final case, when he voluntarily walks into a police station to report his already-ex-girlfriend missing.

He believes he can still control the narrative.
But it is precisely this report that allows police, for the first time, to trace multiple suspicious disappearances and deaths of women—scattered across different cities, different years, different circumstances—back to the same man.

3. Logline

Jordan Liu voluntarily travels to Taiwan to file a missing person report, claiming that his ex-girlfriend Rachel Ling, who was supposed to return to Hong Kong on schedule, has disappeared. After investigating, Taiwanese police discover that Rachel is dead, and the case shifts from missing person to homicide. As Taiwanese and Hong Kong police cooperate in the investigation, they gradually discover that several of Jordan's former girlfriends have also disappeared or died in different cities across Hong Kong, Taiwan, and mainland China—and that his immigration and movement records repeatedly overlap with these cases.

4. Core Thesis

The film's core question is not:

How did he kill?

But rather:

Why did so many people vanish before the world noticed—and why did it take so long?

On a deeper level:

If a man deliberately seeks out people with weak social ties, thin family support, people whose disappearance won't immediately trigger questions—is he truly looking for love, or is he looking for a disappearance the world won't immediately detect?

5. Thematic Keywords

1. Mistaking Love for Possession

The "love" Jordan speaks of is not mature love. It is possession, control, and self-centered attachment.

He is not incapable of loving.
On the contrary, in the early stages of each relationship he may be deeply devoted, attentive, gentle—even convincing the other person that she has finally met someone who truly understands her.

But when the other person begins to carve out space, proposes a breakup, tries to reclaim her own life, his inner love rapidly deforms:

She doesn't want to leave.
She is betraying me.
She doesn't not-love me.
She is negating my entire existence.

So in his mind, a breakup is no longer the end of a relationship—it is the destruction of his identity.

2. Social Indifference and the Delay of Disappearance

The victims in this film are not completely unknown people.

They have jobs, friends, traces of a lived life.
But most of them share common traits:

Fractured or estranged family relationships;
Loved ones not nearby;
Fragmented social circles;
Highly mobile work or living situations;
Habits of cross-city travel, short stays, or dropping off the grid;
Emotional states that outsiders once labeled "unstable";
Disappearances that, in their early stages, are easily understood as "she left on her own."

So their vanishings are not necessarily seen right away.

This is not simply a device to help the killer evade capture. It is the film's social thesis:

Some people are not forgotten only after they disappear—
they are already half-forgotten by the world before they vanish.

3. Guilt, Return, and Arrogance

After each crime, Jordan is not entirely free of psychological residue.

He returns to cities, streets, lodgings, or places he once shared with the victim.
This return is not purely a boast, nor merely a killer revisiting the scene.

It is a mixture of:

Guilt;
Nostalgia;
Confirmation of control;
Self-punishment;
A distorted preservation of the past relationship.

But when he escapes detection time after time, these returns slowly transform into arrogance.

He begins to believe:

It's not that the world hasn't noticed.
It's that I understand better than the world how to make them disappear.

6. Main Character Profiles

1. Jordan Liu (廖子揚)

Age: Approximately 35–40
Identity: Hong Kong male; outwardly ordinary, gentle, high-functioning
Role: Protagonist / person who filed the report / core suspect / central figure in the serial intimate-partner disappearance cases

External Appearance

Jordan is not someone you can identify as dangerous at a glance.

He is neat in appearance, polite in speech, has a stable job, and is not particularly prominent in social settings—but not withdrawn either.
He is not a charismatic demonic type, but a man who is easily overlooked in daily life, and just as easily trusted.

In the eyes of his friends:

Not intense;
Not quick-tempered;
Doesn't cause trouble;
Serious about relationships;
Still cares about his exes after breakups;
Doesn't seem like someone who could hurt anyone.

This ordinariness is his protective layer.

Internal Structure

Jordan's core problem is not simply perversion, nor a pure desire to kill.

His psychological core is this:

He cannot accept that he is not the ending of the other person's life story.

As long as a relationship remains within his control, he can be gentle, patient, attentive.
But when the other person begins to pull away, his inner world collapses with alarming speed:

The feeling of being abandoned;
The feeling of being humiliated;
Possession failing;
Self-worth crumbling;
The other person redefined as a betrayer;
Love transformed into punishment.

He does not intend to kill from the very start every time.
But every time, he fails to stop at the same psychological tipping point.

Character Evolution

After his early crimes, he feels fear, he flees, he returns to old places.
In the middle period, he grows accustomed to making a person's disappearance look plausible.
By the Rachel case, he has become arrogant enough to file a report himself, trying to cast himself as the seeker rather than the sought.

His failure is not sudden stupidity. It is because:

He trusted his past successes too much,
Believing the same narrative could hold forever.

2. Rachel Ling (凌海怡)

Age: Approximately 28–34
Identity: Jordan's ex-girlfriend; the victim in the present case
Role: The final victim / the entry point that unlocks multiple cold cases

External Profile

Rachel is an ordinary, urban woman with a sense of lived life.
She is not completely socially marginalized, nor is she a typical victim template.

She has a job, friends, her own travel habits.
But her family support system is weak, her relationships with relatives are estranged, and there are not many people who would check on her safety every day.

She likes traveling to Taiwan.
For her, Taiwan is not merely a tourist destination—it is a pressure valve.

When life in Hong Kong weighs on her, she will briefly go to Taiwan to clear her head.
Her friends know this, which is why, in the early stages of her losing contact in Taiwan, no one immediately treats it as a homicide risk.

Her Relationship with Jordan

Rachel was drawn to Jordan's attentiveness and stability.
At first, she believed Jordan was a man who knew how to take care of a person—unflashy, unthreatening.

But in the later stages of the relationship, she gradually felt suffocated:

Jordan was overly concerned with her itinerary;
Overly sensitive to her contact with others;
Mixing care with control;
Inwardly refusing to let go even as he outwardly accepted the breakup.

Rachel ultimately decided to end things with Jordan and try to reclaim her own life.

She did not realize that, for Jordan, a breakup was not an ending. It was a trigger.

3. The Lead Taiwanese Officer

Character Function: Driver of the present-case investigation

The Taiwanese officer initially receives an ordinary missing person report.
Jordan is the person filing the report, not a suspect flagged from the start.

But when Rachel's body is found, the missing person case escalates to homicide, and the Taiwanese police begin to re-examine Jordan's reporting behavior, his timeline in Taiwan, and Rachel's final movements.

This officer's function is not to be a genius detective, but to raise the first question from the present case:

Why does this ex-boyfriend know too much, and yet seem too reasonable?

4. The Lead Hong Kong Officer

Character Function: Investigator of Jordan's past relationships and cross-regional movements

The Hong Kong police, contacted by Taiwanese authorities, assist in investigating Rachel's interpersonal network in Hong Kong and Jordan's background.

At first, the Hong Kong police are only providing routine assistance.
But as they review Jordan's past relationships, immigration records, and missing person files, they gradually discover:

Rachel is not the first woman to come to harm after breaking up with Jordan.

The Hong Kong officer's function is to push the present case from a single homicide to a cross-regional serial suspicion.

5. The Gallery of Past Disappeared Women

They may not all appear in full in the finished film.
Some exist only in old news clippings, missing persons records, family interviews, police files, and unsolved death cases.

What they share is not appearance or profession, but:

A prior intimate relationship with Jordan;
Most came to harm after a breakup or a rupture in the relationship;
Their disappearances or deaths occurred in different cities;
Their family support was weak;
Their cases were handled separately at the time and never connected into a whole.

They are the invisible weight of this film.

7. Story Summary

Rachel Ling was originally scheduled to return to Hong Kong from Taiwan, but she did not show up on time.
Her ex-boyfriend, Jordan Liu, after realizing she was unreachable, voluntarily traveled to Taiwan to file a missing person report.

He tells the police that although the two had broken up, they maintained minimal contact. Rachel had always liked traveling to Taiwan, and in the past she had briefly gone off the grid during emotional lows or periods of life stress. But this time was different: she had not returned to Hong Kong on schedule, and she had not replied to messages.

The Taiwanese police initially handle it as a missing person case.
Jordan's role is that of the person who filed the report—the ex-boyfriend, the one who still worries about her.

As the investigation unfolds, police discover Rachel's body somewhere.
The case escalates from missing person to homicide.

The Taiwanese police contact the Hong Kong police and begin investigating Rachel's relationships in Hong Kong.
Jordan is not initially the primary suspect.
But when the Hong Kong police begin reviewing his past relationships, immigration records, and old missing person cases, they find that several women who had been intimately involved with Jordan have disappeared or died in different cities across Hong Kong, Taiwan, and mainland China.

Some of these cases were classified as missing persons.
Some had bodies found but were listed as unsolved.
Some never truly entered the core of a criminal investigation.

When police cross-reference the timing and locations of these women's disappearances against Jordan's immigration and activity records, they find unusual overlaps across multiple critical time periods and cities.

The investigation's direction shifts from Rachel's single homicide to Jordan's years-long pattern of relationships and movements.

In the end, police find evidence in the Rachel case sufficient to establish a direct connection between Jordan and her death.
Jordan still does not realize he has become the primary suspect. He even returns to Taiwan again to cooperate with the investigation.
He believes he can still control the entire story from his position as the person who filed the report.

But this time, after he walks into the police station, he never walks out.

After his arrest, Jordan does not fully confess to all the cases.
He only confronts the Rachel case.

But once in prison, he begins writing a book about "the women he had loved."
On the surface, the manuscript reads like a memoir. In reality, it reveals more cities, dates, locations, and female aliases.

When police cross-reference the manuscript against missing person records from various regions, they reopen old cases one by one.
The remains of women who had been missing for years are found.

Rachel is no longer merely the final victim.
She becomes the entrance to an entire dark map.

8. Three-Act Structure

Act One: The Missing Person Report

Function
Establish Rachel's disappearance;
Establish Jordan's identity as the person filing the report;
Establish Taiwan as the location of the present case;
Make the audience initially believe Jordan is a man who still cares about his ex-girlfriend;
Use the discovery of the body as the Act One turning point.

Main Content

Rachel travels to Taiwan for a trip or a short stay, scheduled to return to Hong Kong on a certain day.
But she does not come back on time. Her phone goes dark. Her social media goes silent.

Jordan notices the anomaly.
He is not her current boyfriend—he is her ex after a breakup.
But he tells those around him that even though they have separated, he cannot pretend not to know.

He travels to Taiwan to file a report.

In the police station, he appears calm, cooperative, organized.
He gives the police details about Rachel's travel habits, emotional state, family relationships, and recent condition.
He repeatedly emphasizes that the two have broken up, but that he still worries about her.

The Taiwanese police initially handle the case as a missing person matter.
Police begin investigating Rachel's accommodation, itinerary, last known location, and interpersonal connections.

At this point, Jordan is not under major suspicion.
He is the person who filed the report. He is an assistant.

In the latter part of Act One, police discover Rachel's body somewhere.
The missing person case officially becomes a homicide.

Jordan's expression remains restrained.
He looks sad—and also as if he had long been prepared for this outcome.

Act One ends.

Act Two: Homicide Becomes a Pattern

Function
Taiwanese police and Hong Kong police cooperate;
Investigate the people around Rachel;
Jordan gradually shifts from the person who filed the report to a person of interest;
The past disappeared women and Jordan's geographic traces are linked;
The single homicide escalates into a cross-regional case of suspicion.

Main Content

Rachel's homicide is covered by the media.
The Taiwanese police contact the Hong Kong police, requesting assistance in investigating Rachel's interpersonal network, work background, family contacts, and the background of her ex-boyfriend Jordan.

At first, the Hong Kong police are merely cooperating.
Jordan has no obvious history of violence in Hong Kong. His job is stable, his social life appears normal, and on the surface he does not seem high-risk.

But in the background check, police discover several anomalies:

Jordan has had intimate relationships with a number of women in the past;
Several of them later went missing, lost contact, or were found dead;
These incidents are scattered across different regions and were never connected at the time;
Because of the victims' estranged family ties, high job mobility, or cross-city habits, some cases were treated as ordinary missing person matters or unsolved cases.

Police begin examining Jordan's immigration and activity records.

He was in Taiwan around the time one woman disappeared.
He appeared in a city in mainland China around the time another woman disappeared.
He had work or short-term activity records near the location of an unsolved female death case in Hong Kong.

Viewed individually, each of these can be explained away as coincidence.
But taken together, the coincidences begin to look unnatural.

The Taiwanese and Hong Kong police gradually exchange information.
A cross-regional timeline is built.

Times, places, intimate relationships, breakups, disappearances—they begin to overlap.

Jordan continues to cooperate with the investigation.
He remains polite, remains calm, even proactively offers information.
But police begin to notice that his account of Rachel is too complete, his familiarity with certain details too precise, and his insistence on the breakup too repeated.

In the latter part of Act Two, police discover a key pattern:

These women did not come to harm during the most passionate phase of a relationship.
They disappeared after the relationship had ended—or was about to end.

For the first time, police truly suspect:

Jordan's danger does not lie in how a relationship begins. It lies in what happens after it ends.

At the end of Act Two, police formally make Jordan the primary focus of the investigation.

Act Three: Chain of Evidence and Arrest

Function
Transform "strong suspicion" into "substantive evidence";
Jordan, in his arrogance, returns to Taiwan to cooperate again;
Police obtain evidence in the Rachel case sufficient to arrest him;
Jordan is arrested;
The prison manuscript exposes more cases.

Main Content

Police understand that the past disappearances and deaths can only establish a pattern—they cannot directly prove that Jordan killed Rachel.

So the focus of Act Three returns to the Rachel case.

Taiwanese police reconstruct the timeline of Rachel's final days.
They find small but significant contradictions in Jordan's account:

He claims he did not know Rachel's whereabouts at certain points, but his activity records show he was near the relevant areas;
He repeatedly says the two had broken up, but Rachel appears to have been avoiding him in the period before her death;
He reacts abnormally to certain details or locations that were never made public;
Some of his actions before filing the report do not resemble a man searching for someone—they resemble a man confirming whether certain things were still safe.

Police build the chain of evidence step by step:

Rachel's relationship with Jordan did not end peacefully;
Jordan's movements in Taiwan around the time of Rachel's disappearance overlap with her final whereabouts;
Jordan's statements are inconsistent with parts of the objective timeline;
Jordan's relationship history shows a recurring pattern of women disappearing or dying after breakups;
In the Rachel case, there is a piece of evidence that directly links Jordan to the crime scene or to contact with her before death.

Jordan does not know how far the police have gotten.
He still believes he is the person who filed the report, the one assisting the investigation, the man who can come to Taiwan, cooperate, and then safely return to Hong Kong.

So he travels to Taiwan again for questioning.

Early in the interrogation, he remains calm.
He repeats his account, stays polite, even shows concern about how the investigation is progressing.

But this time, the police no longer follow his narrative.

They ask about Rachel first.
Then about his itinerary.
Then about his breakup with Rachel.
Then about his past relationships.
Finally, they place the missing person cases from various cities and his immigration records on the table.

For the first time, Jordan realizes the police are not just investigating Rachel.

He still denies everything.
He says those are just coincidences.
He says he just happened to have been to those places.
He says he doesn't know where those women ended up.

Until the police present the direct evidence in the Rachel case.

This evidence may not be enough to prove all the old cases.
But it is enough to prove a direct connection between Jordan and Rachel's death.

Jordan is arrested.

He does not scream or lose control. He does not immediately confess fully.
He is silent for a long time, then says:

"You only found her."

Those words let the police know, for the first time, that Rachel was not the only one.

Epilogue: The Manuscript and the Remains

After Jordan is imprisoned, he does not truly repent.

He begins writing a book.
On its surface, the book is a memoir of his past loves.

He does not use the victims' real names.
He refers to them by cities, seasons, colors, travel locations, rooms, streets, seashores, stations.

But when police read the manuscript, they find that those descriptions correspond with unsettling precision to multiple old missing person cases.

A mountain road mentioned in one chapter corresponds to the final known location of a woman who went missing years ago.
A short-term rental unit mentioned in one chapter corresponds to an unresolved case from that year.
A seaside city mentioned in one chapter corresponds to an ex-girlfriend who was never found.

Police departments across various regions have gradually reopened old cases.

Some of the missing women's bodies have been found.
Others remain unidentifiable.
Some families have received possible answers for the first time.

The film does not end with Jordan's trial,
but with a map that has been re-marked.

Cities across Hong Kong, Taiwan, and mainland China are connected by lines.
The names once seen as isolated disappearances, unsolved cases, accidents, or severed contact are finally placed on the same map.

Rachel's death opened that map.

The film ends.

IX. Narrative Priorities
1. Do not explicitly show every killing

This film does not need to present each victim's death process one by one.
The focus is not gore, but:

how disappearances were rationalized;
how cases were ignored;
how the pattern was pieced together;
how the killer used an ordinary identity to conceal himself;
how society was slow to notice the disappearance of marginalized women.
2. Jordan should not seem too villainous early on

The more ordinary he is, the more powerful the story.

Audiences should understand early on why the police did not immediately suspect him.
He is not an exaggerated madman, but someone who could exist in reality:

ordinary, cooperative, mild-mannered, articulate, even seemingly loyal and principled.

The horror lies in the fact that it is precisely this ordinariness that carries him through suspicion after suspicion.

3. Rachel should not be just a corpse

Rachel must have traces of her own life in the story:

she loved Taiwan;
she wanted to start over;
she decided to end the relationship;
she had her own fears;
she was not simply killed, but had once tried to leave.

She is the entry point into the present case, and the key to the audience understanding Jordan's true nature.

4. Not every old case needs to be explained

The ending can leave gray areas.

Some missing women may be confirmed.
Some can only be strongly suspected.
Some may never be found.

This feels more real than resolving everything.

X. Core Lines

These may serve as the film's internal slogan:

He was not searching for the woman who disappeared.
He was tracking how many people he had made disappear.

Or:

A single disappearance is an unsolved case.
Disappearances across multiple cities, multiple relationships, and multiple breakups only begin to resemble the truth.

Or, colder still:

The ones he chose were all people whose disappearance would not be immediately questioned by the world.
