Following a disagreement between Vinz and Hubert about their perspectives on policing and violence, the two men part ways. Saïd accompanies Vinz, while Hubert briefly returns to his home. They reunite at another gathering in the banlieue, but the situation quickly turns chaotic when Abdel's brother attempts to kill a police officer in revenge. A confrontation with the police ensues, and the group narrowly escapes after Vinz nearly shoots a riot officer. They take a train to Paris, where their responses to both benign and malicious Parisians cause several situations to escalate to dangerous hostility. In a public restroom, a Gulag survivor tells them of a friend who refused to relieve himself in public and subsequently froze to death, puzzling the three as to the meaning of the story.
