Max Fielder (Chevy Chase) is having a terrible day. He hates his job, his girlfriend left him, and on his way home from work a dump truck spills nuclear waste on him and his car. Max regains some optimism after he realizes the fallout from the radiation has given him magical, telekinetic powers! Using these powers, Max attempts to win back his girlfriend by thwarting the attempts of her suitors and exacting a little revenge on all of those poor souls who have annoyed him along the way.
