Elias and Teddy have always been friends. At age 23, they hang out, deal some drugs, and think they are the kings of their very small world. And then one day, for sure, they will leave Limoges for Marseille. Their encounter with Mona is going to speed things up.

Sentenced to six years in prison, Malik El Djebena is alone in the world and can neither read nor write. On his arrival at the prison, he seems younger and more brittle than the others detained there. At once he falls under the sway of a group of Corsicans who enforce their rule in the prison. As the 'missions' go by, he toughens himself and wins the confidence of the Corsican group.

While he loses his clandestine work, and because he believes that Maroussia and him will no longer be able to love each other as well, Frank leaves to earn as much as she: twelve thousand, just what it takes to have a year before them. No more no less.
