The famous scientific detective Justin Crécelle and his faithful assistant Walter Jymson seek to halt the deeds of the "Clutching Foot" gang, who attempt to kidnap Hélène, the fiancée of Justin, in both possible and ridiculous ways. The film is a spoof of the Les Vampires serials, with Musidora appearing in one episode in costume.

Directed by Jacques Feyder.

So, he writes a friend to ask his advice. The friend tries to remake Georges and make him a bit of a playboy. However, when it comes to wooing a rich American, the advice is not exactly perfect.
