The son of a steamboat captain, Buster falls in love with the daughter of a rival steamboat owner. When a cyclone rages, Buster proves himself a hero by rescuing his love and her father from a watery grave. Steamboat Bill Jr has what is surely the most famous Keaton scene of all time, where the facade of a house falls on him and he is uninjured because he passes through an open window instead of being flattened.
