"Chris and his dad have accidentally changed bodies - but no big deal. Chris gets the Jag and the Gold Card. Dad gets the fake ID and the bio final."
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.
