A troupe is fired because, on stage, they did a very bad joke: they locked up the star of the show in her sedan-chair so she could not shine at all. All these boys and girls decide to put on their own show; so they take up residence in an old theater "Elysées-Clichy" and they begin to rehearse their operetta "The crisis is over." But they will have to frustrate their enemy,M.Bernouillin,in his plans.
