Frail, weak and nonathletic Sterling Holloway falls in love with the daughter of a physical-culture expert, Hercules Jones. Jones demands that any man who marries his daughter must prove his worth by meeting him in a wrestling match. The daughter does her best to prepare Sterling for the contest but it all ends in slapstick disasters. Sterling dons an air-inflated suit to meet the father and accidentally wins the bout but a nail deflates his suit.
