When his brother is killed, professional thief Cash (Jean Dujardin) decides his next heist will be robbing the hoods responsible for the death. But to pull it off he'll need some of the best thieves in the business. So Cash assembles a dream team that includes underworld legend Maxime (Jean Reno) ; his partner, Garance (Alice Taglioni) ; and skilled newcomer Julia (Valeria Golino). With such a talented group, Cash's plan is sure to be a success -- except that one of them is an undercover cop.
