While on a top-secret mission in Sector 4, the most dangerous area of the Middle East, a team of Private Military Contractors known as Black Knight are ambushed and taken hostage. Team leader Nash Olsen (Olivier Gruner) escapes captivity and is rescued by the U.S. government, only to discover by Black Knight Commander (Eric Roberts) that a rescue mission is impossible. Forced to choose between his family or upholding the Black Knight motto "No One Left Behind," Nash begins a one-man rescue attempt to save his team, discovering there may be more to this mission than he thinks.
