The general premise is established within the first fifteen minutes: Malik El Djebena (Tahar Rahim) arrives at prison to serve six years for a crime never referenced in the film and to which Malik, at least at one point, claims innocence. He arrives without connections, family, or any semblance of a past life beyond the cuts and scars on his body. Locked away, he quickly finds himself a lone target for hardened cri minals.
Meanwhile, the rivalry between Corsican and Muslim inmates escalates as a new Arab prisoner is housed in the Italian block. The Corsican boss, César Luciani (Niels Arestrup), has been ordered to have this new prisoner killed before he can testify against the mob leaders on the outside. Malik is quickly told that he will be the one to do the job. Malik is an Arab, and can gain the trust of the Muslims easily. If he does not kill the new prisoner, the Italians will kill him in return.
This all happens within the first fifteen minutes, and is quite easy to follow. Malik shows some hesitation, but by minute twenty, begins to carry out the assignment. It’s an awkward, bloody murder and Malik is consequently haunted (literally and figuratively) by his actions.
The next two hours of the film charts Malik’s continual integration into the politics of prison life. He works first as a grunt for the Italians, learning to read and gaining friends, and eventually becomes quite proficient at a spectrum of crimes, from dealing drugs to ritualistic killings, and thrives by criminal activity.
The script might easily have been adapted into a miniseries, an episode for each of the six years of Malik’s imprisonment perhaps. The episodic structure of the film has a string of events which could have easily been shuffled, deleted, or combined with little effect on the end result. The events held little importance beyond showing Malik’s gradual ascension into criminal competency. There was no “big score” or rite of passage, and some of the side plots, like Malik’s visit to a friend with testicular cancer, seemed completely unnecessary.
