Dr. Jack Hammond has best chances to become medical superintendent at his clinic, so he's completely absorbed in his work and has no understanding of 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 at school and work, but also to insight into each other's problems and feelings.
