Henry Spivey (Christian Slater) is an average thirtysomething, middle class man, living in the suburbs with his wife and two kids. Edward Albright, a trained-to-kill operative fluent in 19 languages, is the polar opposite of Henry; however, they have one thing in common -- the same body. When the wall between Henry and Edward begins to break down, each man is placed in a very unfamiliar environment forcing them each to wonder who they can trust when they can't even trust themselves.
Edward figures a way to change identities on his own, but it may be risky. Tom meets up with a stranger who is aware of his alter ego, and Edward is sent on a secret mission by Mavis and Alistair on his own without the usual backup.
