After a successful heist, Franck Adrien and his partner are convicted and sent to prison. Adrien is the only one who knows the location of the stash, and he refuses to tell both his wife and his partner. However, despite his initially aloof relationship with Jean-Louis Maurel, Adrien comes to trust his cellmate and saves him from a savage beating by Russian mobsters. When Adrien's former partner puts him in the prison hospital, Maurel visits Adrien. Although Adrien does not trust Maurel enough to reveal the location of his stash, Adrien gives Maurel a hint to pass along to Anna, Adrien's wife, as Maurel is being released early due to his alleged victim recanting her charges of rape.
