Jack Collins (Milo Gibson), a former Navy SEAL turned bounty hunter, tracks down terrorists in missions so hazardous that the CIA outsources them to private companies. But a life spent surviving fraught situations has left its mark on Collins, leading his CIA handler Leigh (Sylvia Hoeks) to offer him one last chance to keep fighting. Deployed as part of a hardened three-man team (William Fichtner, Gbenga Akinnagbe) to hunt down a rogue operative in London, Collins finds himself locked in relentless urban tactical combat, fighting a superior force alongside his own personal demons.
