They picked the wrong man to clone.
A world of the very near future in which cattle, fish, and even the family pet can be cloned. But cloning humans is illegal - that is until family man Adam Gibson (Arnold Schwarzenegger) comes home from work one day to find a clone has replaced him. Taken from his family and plunged into a sinister world he doesn't understand, Gibson must not only save himself from the assassins who must destroy him to protect their secret, but uncover who and what is.
