Out jogging, the Optimist (Enn Reitel) realizes he's unfit, but when a doctor enrols him at a health farm, he soon discovers the place is more like a prison run by the scary Matron (Fran Ryan). He's half-starved, tortured in the gym, physically battered in an all-ladies aerobic session, and cut down in a karate class. Despite this, he falls for a Dancer (Terri Robinson) and devises a plan to escape with her help, using a multitude of disguises and the local fire department. Finally, he makes a bid for freedom, jogging into the sunset with the girl of his dreams.
