Before the title credits roll, the film opens with a prison guard drafting a report about a death found in one of the cells, marking the cause as a suicide. The scene suggests that this tragedy is connected to the events that will unfold, even though the full chain of cause and effect isn’t stated outright. This prologue casts a shadow over what follows, hinting at the moral and social consequences simmering beneath the surface of prison life.
On a very rainy evening, Łukasz Machnacki steps out of a cinema and is immediately corralled by the police. He is handcuffed and hauled into a squad car, then thrust into a police lineup where he’s identified by an elderly robbery victim. He protests his innocence, but with no solid alibi to offer, he is arrested and told that his freedom will depend on a lengthy investigation. The shock of the moment leaves him reeling as the reality of a harsh future in custody begins to sink in.
Once in custody, Łukasz is placed into a transition cell, where he meets Zborek, a man jailed for car theft. Zborek explains the brutal pecking order inside prison and presses Łukasz to join the notorious grypsera—an inmate subculture that commands respect and protection. He warns that if Łukasz refuses, he risks becoming a target and a “loser.” Faced with this stark choice, Łukasz agrees to enter the grypsera, a decision that surprises a staff interviewer who doubted he’d go along with it. But the arrangement is quickly sealed, and Łukasz finds himself moved into a cell where the subculture already holds sway.
In the new cell, the dynamics are immediately clear. The apparent leader, Kosior, governs with a confident, threatening calm; Siwy stands as a tough member of the group; Albert is a younger, volatile presence; Roman sits lower in the hierarchy, often overlooked; and Dawid is the quiet bookish figure whose restrained demeanor earns quiet respect. Albert’s teasing, and Siwy’s challenge to Łukasz’s willingness to prove himself, set the tone for how the new inmate must navigate this rough, unwritten code. Roman patiently teaches the everyday rules, while Kosior lays out the deeper code of the grypsera, explaining how to survive in this environment.
A lawyer hired by Łukasz’s mother drops by to deliver news from outside. The prosecutor is weighing charges that extend beyond robbery to unintentional homicide, after the elderly witness who identified Łukasz dies shortly thereafter. The lawyer pledges to push for Łukasz’s release, but he warns that the process could take months. The legal question hangs over the block, compounding the psychological strain of prison life.
The following days bring a stark glimpse into the violence beneath the surface. Albert recounts a disturbing tale about abducting a girl for sex, and Dawid reels against it, grabbing Albert in a threat that makes clear the stakes of any loose talk. The next day Kosior explains Dawid’s past violence in context, and Łukasz observes weekly visits from Dawid’s wife. The two share a gaze rather than words, hinting at a relationship strained by fear, propriety, and the unspoken pressure of life behind bars.
Nightmares haunt Łukasz as he tries to adjust, and a brutal disciplinary measure—being forced to drink a detergent mixture as punishment for breaking a minor rule—remains a painful memory. A guard then announces Łukasz’s release, only to pull it back at the last moment: the door opens and then closes, and the cruel joke leaves him devastated, pushing him toward a suicide attempt. The resilience necessary to keep going is tested to the limit.
After this crisis, Łukasz begins to accept his situation and study the grypsera’s rules with Kosior. He earns formal acceptance as a member of the group, and even wins some respect from Albert by turning a piece of Albert’s contraband to his own advantage when it’s discovered by an officer. The once-terrifying environment becomes a familiar, albeit clawing, social order where survival often hinges on wit and nerve.
When Łukasz’s trial finally comes around, Siwy is transferred out and a new inmate arrives in the cell: a man accused of child sexual abuse. Kosior does not tolerate any noise, and the guards do little to intervene as the new prisoner is subjected to humiliation and rough treatment. The shift starts to test the loyalties and nerves of all involved, especially Łukasz, who has to weigh his own safety against the moral cost of staying true to the group.
Then comes a thread of hope. Łukasz’s attorney brings news that the prosecutor plans to remit the case due to lack of evidence, hinting at an imminent release. The family drama intensifies as his mother and younger sister visit, creating a tense, emotionally charged moment in which Łukasz—watching the accused man nearby—tells his family to leave, and that he loves them.
The potential release stirs dangerous plans within the cell. Albert suggests killing the man and making his death look like a suicide, a lurid idea that Kosior condones. Łukasz hesitates, but Kosior presses him by appealing to his protective feelings for his sister. Roman resists, but Albert threatens him with harm if he objects. That night, Łukasz knocks Roman out with a chair to reduce the risk of interference, and the group proceeds to murder the new prisoner—strangling him and hanging the body from the window bars to suggest a suicide.
In the aftermath, Łukasz’s mother returns for another visit, this time through a glass partition with a phone. She is overwhelmed with worry and grief as Łukasz tries to explain that life in prison operates on a different logic that she would not understand from the outside. He ends the call with a quiet, heavy confession about the choices he has made and the distance that now lies between them.
