Buster Keaton plays the wimpy son of 'Steamboat Bill' Canfield, a salty tugboat captain, in this silent classic. The younger Bill spends most of his time trying to live up to his father's tough expectations. Then, to make matters worse, he falls in love with the daughter of the old man's fiercest rival-only to end up coming to everyone's rescue in the movie's heroic ending. Contains one of the most famous (and dangerous) scenes in silent film history-that of Keaton escaping the crush of a collapsing building when he happens to stand in the same exact spot as the window frame.
