Une nuit au Moulin-Rouge

An uncle in America wants to endow his nieces with a dowry, provided they succeed in making a name for themselves one night at the Moulin Rouge, where one of them is already performing. Everyone's pulling out all the stops to help the girls put on an act, dupe the theater manager and win the dowry - which will be doubled if they manage to marry, as their uncle is marrying the star of the show.
