Suicide Club

On May 27, 54 teenage girls die by mass suicide in Tokyo, throwing themselves in front of a train. At a nearby hospital, two nurses die by suicide as well. Rolls of skin are found at both locations, matching the skin removed from the dead. Detectives Kuroda, Shibusawa, and Murata are alerted by hacker Kiyoko to a link with a website that shows suicides as red and white circles.

The detectives learn from Kiyoko that the suicides are connected to a mysterious Suicide Club and a public website with red and white circle motifs. They begin to investigate the online link and coordinate their response to the growing crisis. The online clues propel the case forward.

On May 28, a group of high school students jumps off a roof during lunch, prompting citywide searches for a rumored Suicide Club. The incident signals that the online link is more than a curiosity and that danger is spreading. The authorities begin to tighten the investigation across multiple locations.

By May 29, suicides spread across Japan at an accelerating pace. Mitsuko is on her way home when her boyfriend Masa throws himself off a roof. At the police station, Mitsuko is strip-searched and a butterfly tattoo is discovered.

On May 30, the police receive a phone call warning that another mass suicide will occur at 7:30 on the same platform. The detectives organize a stake-out to prevent it, but no suicide happens that night. Meanwhile, smaller-scale suicides continue nationwide, claiming more lives including Kuroda's family.

That evening, Kuroda learns that his entire family has died as the suicide wave unfolds. He receives the warning call and, overwhelmed by grief, shoots himself. This personal catastrophe underscores the reach of the crisis.

Kiyoko is captured by Genesis, a group led by a man named Genesis, who hides in a subterranean bowling alley with four glam-rock followers. During the capture, Genesis performs a song while a girl in a white sack is brutally raped and killed in front of them. Kiyoko emails authorities with information about Genesis.

On May 31, the police arrest Genesis, and it is assumed the leader of the Suicide Club has been caught. The arrest provides a turning point in the investigation, though the true mastermind behind the suicides remains unknown.

On June 1, Mitsuko goes to her boyfriend's home to return his helmet and notices Dessert posters. She recognizes a pattern on the group's fingers that matches letters on a telephone keypad spelling suicide. The boyfriend denies any Suicide Club and invites her to a secret concert.

On June 2, Mitsuko sneaks into the backstage area and encounters a group of children in the audience who question her. A strip of skin from her butterfly tattoo is shaved off to reveal the tattoo's location.

A new roll of skin ends up with the police, and detective Shibusawa identifies the strip as Mitsuko's tattoo. That evening, he sees Mitsuko at the train station and grabs her hand, but she pulls away, staring as the train pulls into the station.

As the ending credits begin, Dessert announces their disbandment and performs their final song, Live as You Please, thanking their fans for their support. The film closes on Mitsuko's unresolved fate and the lingering mystery of the Suicide Club.
