Retribution

An unknown woman in a red dress is found drowned on the Tokyo waterfront. The autopsy reveals seawater in her stomach, suggesting drowning. Yoshioka begins a tense investigation and pushes for answers, even as his memory remains murky. The case seems to be steering toward him, though he cannot recall the crime.

Buttons and fingerprints link the murder to Yoshioka: a button from the scene matches one missing from his coat, and his fingerprints appear on key evidence. The mounting links force him to confront the possibility that he is the killer. But he has no memory of committing the crime. The investigation becomes a race against his own vanished past.

A ghost in a red dress begins appearing to Yoshioka. The apparitions grow more intense as the clues pile up and the city feels less safe. He struggles to separate reality from illusion while the case spirals toward him.

More murders occur where loved ones are killed for small infractions. Yoshioka tracks these incidents and uncovers the same pattern as the original case. The disturbing trend ties back to the ferry routes past the same asylum.

Authorities identify the drowned woman, confirming her identity and pushing the case toward resolution. Yoshioka digs deeper, sensing that understanding her death will unlock the truth about himself. The sense of inevitability grows as more connections surface.

Yoshioka visits the drowned woman's parents and learns she had a boyfriend extorting their family. The boyfriend arrives at the house at the same time and confesses to the crime. The revelation deepens the web of guilt surrounding the case.

The ghost reveals she is not the murdered woman but the ghost of a woman Yoshioka saw fifteen years ago in an asylum window who has since died. She explains that all the murderers took the ferry past the same asylum. The revelation reframes the entire case and his guilt.

Fearing what he might do to his girlfriend, Yoshioka sends her away. He continues his hunt for clues, growing increasingly isolated and haunted by the visions.

He goes to the asylum, where the woman in red forgives him for not helping her fifteen years ago. The forgiveness offers a brief solace, but it does not erase his guilt.

Back home, Yoshioka discovers that he murdered his girlfriend six months ago. The shocking memory surfaces, driving him toward madness as he tries to piece together the missing hours.

He begins collecting bones and travels to the asylum to retrieve the ghost's bones. The act deepens his break from reality as he clings to the physical remnants of the crimes.

Yoshioka’s partner arrives at his apartment and finds the empty bowl that he used to commit the murder. The ghost stalks him as ominous tremors shake the building. An earthquake strikes, the bowl fills with water, and the ghost drags them both toward the bowl.

The film ends with Yoshioka walking the city street carrying a bag containing his girlfriend's bones and the ghost's bones. The ghost repeats a chilling line about being dead and wishing everyone else to die too. The final image hints at an endless cycle of guilt and tragedy.
