Condemned to six years in prison, 19-year-old Malik El Djebena cannot read or write. Arriving at the jail entirely alone, he appears 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.
