Malik El Djebena, a 19-year-old of Maghrebi descent, is sentenced to six years in prison for attacking police officers. Arriving alone and illiterate, he quickly falls under the sway of Corsican mobsters led by César Luciani, who enforce a brutal, unyielding order within the walls. The prison itself is split between two dominant factions—the Corsicans and the Maghrebis—and Malik largely keeps to himself, trying to survive in a world that sounds harsh and unforgiving.
When Luciani compels him to become the unwilling killer of Reyeb, a Maghrebi witness in a trial, Malik unexpectedly gains the Corsicans’ protection despite his North African origins. He becomes a low-ranking servant to the Corsican regime, enduring disdain while the memory of Reyeb’s murder gnaws at him from the inside. As the Corsicans move many of their members or free them, Luciani elevates Malik, turning him into his eyes and ears inside the prison and teaching him the Corsican language in secret so he can operate more effectively.
With Malik earning day-long furloughs outside the prison, Luciani increasingly relies on him to run criminal operations beyond the bars. A pivotal friendship forms when Ryad, a Maghrebi ally, teaches Malik to read and write, opening his world and expanding his influence. Ryad introduces Malik to Tarik and Hassan, two fellow Maghrebis, and Malik’s power within the prison grows along with his sense of belonging to his community. Malik also becomes entangled with a prison drug dealer named Jordi, and when Ryad receives an early release due to cancer, the three men embark on a hashish-trafficking venture that extends beyond the prison walls.
The bond among them hardens when Ryad is kidnapped by Latif; Malik mounts a daring response by tracking Latif’s r relation inside the prison, and he forces Latif’s gang to release Ryad by taking the relative’s family hostage. Luciani, alarmed by Malik’s growing autonomy and the danger of a real challenge to his authority, administers punishment—forcing a spoon into Malik’s eye as a brutal reminder of who holds power.
A crucial turn comes with Malik’s assignment to meet Brahim Lattrache in Marseille, a Maghrebi figure connected to a deal with the Lingherris, the Italian mafia. Lattrache resents the Corsicans for Reyeb’s murder and initially holds Malik at gunpoint. A moment of superstition—Malik remembers a deer warning sign from a dream—persuades Lattrache of Malik’s unusual potential, and Lattrache decides to work with Malik instead of Luciani, even though Malik admits he killed Reyeb. This moment reshapes Malik’s path, but Luciani remains intent on rooting out a hidden mole and uses Malik to target Jacky Marcaggi, the Corsican don.
Malik and Ryad subvert that plan: they eliminate Marcaggi’s bodyguards, seize Marcaggi himself, and tell him that Luciani ordered the hit—then abandon him in the city, ensuring the two Maghrebi men retain control and protect their own interests. Malik seeks refuge at Ryad’s home, where the cancer that has haunted Ryad returns, and Ryad asks Malik to promise to take care of his wife and child after he is gone.
Back inside the prison, Malik is placed in solitary for returning late, a move that further destabilizes Luciani’s grip as Marcaggi’s influence wipes out Luciani’s faction in the broader power structure. When Malik finally returns to the general population, he joins the Maghrebi faction in the yard as its new leader, while Luciani’s authority withers under the pressure of an organized, militant Maghrebi presence.
On Malik’s release day, he is greeted by Ryad’s wife and son outside the gates, and together with his new associates, he steps into a future shaped by the power he has carved out—an uneasy triumph born of violence, loyalty, and a relentless drive to outrun a past he cannot forget.
