A fascinating look into the French prison system.
A terrific young actor named Tahar Mahim plays Malik, an Arab teenager sentenced to six years in prison. He's drafted by a Corsican gang that practically runs the prison to kill a fellow Muslim inmate who plans to act as a witness as part of a plea bargain. Once he does that he earns protection from the Corsicans, even though they continue to treat him like a servant because he's Arab, but because of their protection he's able to use his wiles to rise through the criminal ranks and emerge from the prison a major crime boss.
"Un Prophete" uses the prison setting to serve as a microcosm of French culture and current racial conflicts between the French and Arab immigrants. Mahim isn't educated, but he's smart, and he knows that to declare allegiance to either side is to limit his ultimate potential. Mahim gives an amazing, unshowy performance; it's largely because of him that the scene in which he carries out the hit is such a nail biter.
One brief scene late in the film suggests that there might be a literal meaning to the film's title, but overall the meaning is thematic -- Malik becomes a prophet to his people, but his story illustrates that not all messages carried to us from prophets are necessarily positive ones.
