On a chilly Helsinki morning, a decomposed body found in the harbor, dressed only in red swimming trunks, launches a careful and patient investigation led by forensic dentist Oili Lyyra and her dedicated detective partner and lover Eero Harakka. The case immediately pairs Oili with the pathologist Lipponen, whose expertise helps piece together the clues surrounding the unidentified corpse.
As the mystery unfolds, Oili encounters the circle around Laura Laura Lyyra, Laura Lyyra’s sister, a young woman who feels lost after leaving medical school five years prior. Laura is insecure and resents the protective stance Oili has always taken, a dynamic that nudges her toward the radical circle led by the charismatic Maaru Tang. Maaru is a renowned author and public speaker who frames fear as a political act, and she and her followers invite Laura into their fold as they stage a chilling critique of male violence.
The group’s plan shocks Oili when they reveal to her that they killed the harbor man—not for random violence, but as a calculated message aimed at teaching a lesson about how women are treated. The confession carries a brutal twist: the plan was executed, but the man died of a heart attack in the process. The revelation lands with a jolt, and Oili realizes, with mounting dread, that Laura herself was involved in the scheme. The admission comes with a brutal moral cost, and the pressure mounts as the group tries to keep the truth hidden and maintain their crusade.
The stakes rise when Laura becomes a target of a vicious attack, a stark reminder of the real danger that accompanies online-style crusades and street-level vigilantism. At the same time, the group puts pressure on their next potential victim, driving instructor Rainer Sakari Auvinen into their crosshairs, signaling that their campaign against perceived female oppression is far from over.
Caught between duty and family, Oili faces a perilous choice: shield Laura to preserve their bond, or reveal the truth to safeguard potential victims and the wider public. The tension intensifies as the feminist group grapples with its own fear—not of the violence they claim to oppose, but of exposure and the unraveling of their authority to continue their self-styled crusade against male violence.
The narrative threads together a stark meditation on loyalty, responsibility, and the slippery line between protection and complicity. In a city that hums with everyday life, the case exposes how quickly fear can morph into a force that challenges personal ethics, professional duty, and the uneasy balance between justice and vengeance. Amid the fog of political rhetoric and personal loyalties, the film keeps its focus on the human costs of radical activism, the fragility of trust, and the difficult choices that define the characters' futures.
