As America reels from the bizarre presidential assassination committed by a child, seven men are abducted from their normal lives and delivered to a top secret government facility. Each man has his own career, his own specialty. All are identical in appearance. The seven strangers soon learn they were not born, but grown as part of a project called 7th Son. The government now wants something from these 'John Michael Smiths'. They share the flesh and implanted memories of the psychopath responsible for the president's murder. The killer has bigger plans, and only these seven have the unique qualifications to track and stop the madman - and his growing army of identical, remorseless assassins. But when their progenitor makes the battle personal, it becomes clear he may know the seven better than they know themselves.
