When FBI agent Roy Clayton heads up the investigation into a dangerous international conspiracy, all clues seem to point back to former U.S. Special Operations officer, Samir Horn. A mysterious figure with a web of connections to terrorist organizations, Horn has a knack for emerging on the scene just as a major operation goes down. The inter-agency task force looking into the case meets with Carter, a veteran CIA contractor who seemingly has his own agenda and fellow FBI agent, Max Archer. The task force links Horn to a prison break in Yemen, a bombing in Nice and a raid in London, but a tangle of contradictory evidence emerges, forcing Clayton to question whether his quarry is a former military operative or something much more complicated.
