After well-to-do bookseller Edouard Lestingois (Charles Granval) rescues a tramp from a suicidal plunge into the Seine, his family adopts the bum and dedicates itself to reforming him. The irrepressible Boudu (Michel Simon) shows his gratitude by shaking the household to its foundations, challenging the hidebound principles of his hosts and seducing them with his anarchic charm. With Boudu Saved from Drowning, legendary director Jean Renoir takes advantage of a host of Parisian locations and a brilliant performance by Simon to create an effervescent satire of bourgeois complacency.
