When FBI agent Roy Clayton (Guy Pearce) heads up the investigation into a dangerous international conspiracy, all clues seem to lead back to former U.S. Special Operations officer Samir Horn (Don Cheadle). A mysterious figure with a complex web of international connections, Horn has a knack for emerging on the scene just as a major operation goes down and disappearing before the authorities can question him.

The inter-agency task force looking into the case meets with Carter (Jeff Daniels), an amoral, veteran CIA contractor who seems to have his own agenda, and FBI agent Max Archer (Neal McDonough). The task force links Horn to illicit activities in Yemen, Nice and London, but a tangle of contradictory evidence emerges, forcing Clayton to question whether his quarry is a disaffected former military operative -- or something far more complicated.

Obsessed with discovering the truth, Clayton tracks Horn across the globe as the elusive ex-soldier burrows deeper and deeper into a world constructed of secrets and lies.
