Condemned to six years in prison, Malik El Djbena cannot read nor write.
Arriving in prison at the age of 19 he is much younger and more fragile than the other convicts.
Cornered by the leader of the Corsican gang who rules the prison, he is given a number of "missions" to carry out, toughening him up and gaining the gang leader's confidence in the process.
But Malik is brave and a fast learner, daring to secretly develop his own plans...
With an award-winning performance from rising star Tahar Rahim.
Director: Jacques Audiard
