A young college graduate faces some difficult choices in this thriller set in the world of online gambling. When Ritchie (Justin Timberlake) is cheated out of the money he had earmarked for his tuition fees on an online poker game, he sets out for Costa Rica to confront the site's owner, ruthless gambling tycoon Ivan Block (Ben Affleck). It's not long, however, before Ritchie, seduced by the promise of untold wealth and status, is lured into becoming Ivan's protégé and right-hand man. But when the FBI, in the shape of hard-bitten agent Shavers (Anthony Mackie), pressures him into helping to bring Ivan's empire down, Ritchie finds himself between a rock and a hard place, forcing him to use all of his wits and cunning to stay alive.

Gavin O'Connor directs this action Western. Natalie Portman stars as Jane Hammond, gun-wielding wife of Bill 'Ham' Hammond (Noah Emmerich). When Ham is severely injured in a duel with the Bishop Boys, a band of thugs headed by the devious Colin (Ewan McGregor), the couple go on the run. With the gang hot on their heels, Jane turns to old flame Dan Frost (Joel Edgerton) to help the pair stake out against the approaching mob, whose past with Jane goes deeper than is at first apparent.
