Dr. Sean Jamison (Brian Keith) responds to a sick call at Camp Olahino and is shocked to discover it is a nudist colony. Dr. Sean's problems mount when he loses Stewart (Sean Tyler Hall) in the crowd and when Puni (Victoria Young), his nurse, and Dr. Anne (Shelley Fabares), his daughter, arrive unexpectedly to help. His crowning shock comes when the camp honors his colleague, Dr. Chaffee (Roger Bowen), the last person he expects to see. Nancy Kulp co-stars in her regular role of Mrs. Gruber.
