Alex Lewis (Liam Neeson) is an expert assassin with a reputation for discreet precision. When Alex refuses to complete a job for a dangerous criminal organisation, he becomes a target and must go on the hunt for those who want him dead. Veteran FBI agents Vincent Serra (Guy Pearce), Linda Amistead (Tai Atwal) and Mexican Intelligence Liaison Hugo Marquesz (Harold Torres) are brought in to investigate the trail of bodies left in Alex’s wake. With both the crim syndicate and FBI in hot pursuit, Alex has the skills t stay ahead, except for one thing – he is struggling with severe memory loss, affecting his every move and making his objective increasingly difficult to complete. As details blur and enemies close in, Alex is forced to question his every action, and who he can trust.
