SET-UP: Tom Berenger has a disfiguring car crash and loses his memory. After re-constructive plastic surgery, he learns that his 'caring' wife was cheating on him.
TWIST: Tom Berenger isn't Tom Berenger at all. He discovers his OWN dead body and finds out he's actually the guy his wife was having an affair with. The plastic surgery changed his face to look like him.
PROBLEM: Ermm, his voice? His body? His height? His hair? Does plastic surgery sort all that out as well?
