In its well-written first hour, writer-director Jeffrey Nachmanoff's thriller hops nimbly across continents, juxtaposing terror-cell intrigue with moments of self-reflection from FBI men and bad guys alike. Traitor's man on the run is Samir Horn (Don Cheadle), an American-born mercenary who at age nine witnessed his Sudanese Muslim father being blown to bits in a Middle Eastern car-bomb explosion. The culprits are unknown, but years later, Samir is in Yemen, selling Semtex explosives to jihadists. Samir has a tendency to stare off into the distance—a Cheadle specialty—mulling over, perhaps, his time as a U.S. Special Forces soldier, a job (and a country) that he turned his back on after a tour of duty in Afghanistan led him to become an Islamic fundamentalist. The movie's first hour is well-done, but realism and insight go out the window as soon as Samir crosses the U.S. border—oh so easily—to set in motion one last big terror plot, a plan that actually calls to mind the scheme from Don Siegel's far superior 1977 thriller Telefon, in which a rogue KGB agent travels across America activating deep-cover Russian agents. Nachmanoff has devised a nifty last-minute twist to the concept, but he appears to take little pleasure in the telling—almost if he's embarrassed to be having fun with a subject as serious as terror. Creating an ingenious mad bomber isn't quite the thrill it used to be. — Chuck Wilson
