#1 Serial Killer

In the quiet before the main events, Eddy immerses himself in material about serial killers and dangerous minds. He visits a macabre store to collect relics and tests boundaries with a homemade mannequin bearing his father's face. He erases his mother's messages and builds a cold, self-justifying narrative about his own capacity for fear-based control.

A new associate from Hong Kong, Karena Lee, arrives at the office, drawing curious glances from Eddy and his colleagues. Mr. Chang notes something off about Eddy even as he praises early success as a path toward management. The office hums with humor, tension, and hints of cultural clash as dynamics form.

Karena attempts to bridge cultural gaps while Eddy remains guarded and self-contained. At lunch, coworkers tease Eddy as he studies serial killers, foreshadowing his growing instability. Karena longs for connection and safety in Eddy's company, deepening a dangerous dynamic between them.

Amber Sterling's social world continues to unfold, but the simmering tension around Eddy foreshadows a pattern of control that will erupt later. The narrative quietly sketches how ordinary interactions can mask a fatal mindset. Amber remains distant from the office drama, yet she becomes a focal point of the book's looming threat.

In the parking garage, Amber exits the building and heads toward her SUV when a man in black with a white mask grabs her by the hair and presses a knife to her throat. He whispers in an Asian accent, forcing her into the car with chilling calm. The sequence is breathless, shocking, and establishes the fear-driven pattern the film will explore.

Back at the office, a police officer questions Eddy about his whereabouts during the crucial time, and Eddy's discomfort hints at something deeper. Detectives piece together the timeline from videos and images detailing Eddy's fixation on killers and victims. The office atmosphere tightens with suspicion as the mystery deepens.

Karena and Eddy's fragile bond evolves into something more intimate and dangerous as Eddy's obsession with Karena grows. They fantasize about killing Mr. Chang, with Eddy urging Karena to imagine herself as a killer in a symbiotic partnership. The relationship becomes a study in coercive romance, control, and deadly fantasy.

The tension crescendos when Eddy stages a dramatic act that removes his mentor from power. The confrontation marks a turning point, revealing Eddy's willingness to seize control and redefining his relationship with Karena. The act demonstrates a ruthless calculus that blends ambition with violence.

Eddy and Karena formalize a dangerous plan to keep Karena close through crime, rehearsing and enacting sequences of violence that blur lines between protector and predator. They cultivate secrecy and a shared creed that elevates fear as a tool of power. The fantasy of murder becomes a tangible, rehearsed reality.

Investigators amass a wall of images and a string of videos detailing Eddy's fixation on killers and victims. Tricia Arnold and other coworkers weigh Eddy's polished persona against the mounting evidence of his dangerous secret. The timeline begins to close in on Eddy as the truth threatens to surface.

In a final, brutal coda, a routine car start fails for Tricia Arnold, and the killer emerges from the backseat to strangle her. Karena records the scene, turning the event into a witness and extending the couple's terrifying footprint. The camera's gaze seals a new chapter where violence hides behind courtesy and control remains coercive.

The film closes with a lingering sense that Eddy and Karena's power dynamic will continue to haunt others. The audience is left with the fear that violence can be intimate and that a calm exterior can mask a dangerous, ongoing threat. The final frame suggests the potential for fear to persist beyond the story's end.
