A contemporary caper set in L.A. about an odd con-artist couple, Rodrigo (Diego Luna) a rookie conman desperate for money to help his family, and Richard (John C. Reilly) the seasoned pro who wants to get rich in any way possible. When they come across one of the most valuable pieces of currency in U.S. history, they're suddenly stuck together in the con of their lives. All they have to do is sell it, which is where the real problems begin. The one person who can help them, hates them - Richard's long suffering sister (Maggie Gyllenhaal). Luckily there is an antique currency collector in town (Peter Mullan), but nothing is ever that easy...In this twisty tale, can you tell who's conning who?
