It's hard to tell the good guys from the bad guys in this slick, densely plotted thriller from France. Cash (Jean Dujardin) is a suave and well-mannered outlaw who specializes in grand-scale heists that turn on carefully constructed confidence games as much as muscle. When Cash's brother and partner in crime Solal (Clovis Cornillac) is killed by members of a rival outfit who try to force their way into a carefully planned heist, Cash assembles a new crew to rob the gunmen for their ill-gotten gains. Cash joins forces with Maxime Dubreuil (Jean Reno), a gifted veteran thief who brings along his beautiful protégé Garance (Alice Taglioni). As Cash, Maxime and Garance map out plans for the robbery of a lifetime, they're joined by Julia (Valeria Golino), a beautiful woman with a full compliment of criminal skills. But what they don't know is that Julia is actually an undercover police officer who is looking to shut down Cash's operation from the inside. Cash was written and directed by Eric Besnard; it was his second feature as director after establishing himself as one of France's leading screenwriters.
