The anxious, clumsy and abused office clerk Wesley Allan Gibson has a hell and boring routine life: his obese boss humiliates him all the time and his girlfriend betrays him with his colleague and best friend during working period. When he meets the sexy Fox, Wesley is informed that his father was a professional killer that belonged to an ancient organization called Fraternity and killed by the skilled and powerful Cross, a hit-man that has betrayed the Fraternity. Wesley learns that his anxiety actually is a manifestation of his latent abilities and he joins the society under the command of Sloan. Trained by Fox, he changes his personality and attitude, being prepared to face the dangerous Cross and find a hidden secret.

This is Director Timur Bekmambetov's first American film.

Sloan:
It a choice, Wesley, that each of us must face: to remain ordinary, pathetic, beat-down, coasting through a miserable existence, like sheep herded by fate - or you can take control of your own destiny and join us, releasing the caged wolf you have inside. Our purpose is to maintain stability in an unstable world - kill one, save a thousand. Within the fabric of this world, every life hangs by a thread. We are that thread - a fraternity of assassins with the weapons of fate. This is the decision that lies before you now: the sheep, or the wolf. The choice is yours.

Continuity: When Wesley Gibson is tied to the chair and punched in the face, a cut on the bridge on his nose disappears and re-appears in some shots.

Written by Mildred J. Hill and Patty S. Hill
