After being sent to the electric chair, a serial killer uses electricity to come back from the dead and carry out his vengeance on the football player who turned him in to the police.

Dr. Jack Hammond has best chances to become medical superintendent in the clinic. So he’s completely absorbed in his work and has no understanding for his teenage son Chris’ problems with school. By accident one of them drinks a brain-exchanging serum, and it switches their identities. This leads of course to extraordinary complications in school and at work, but also to insight in the problems and feelings of each other.
