It is Christmas Eve in the tropical prison colony of Cayenne. Felix Dulay, a hopeless storekeeper and businessman, and his long suffering wife Emilie are fearfully awaiting the arrival of Felix's brother, Gaston who has financed the shop. Providence has given the Dulays three guardian angels - three convicts! In no time they have cooked Christmas lunch - and Felix's books - rescue a romance and deal with the wicked Uncle Gaston in their own special way! Such is the popularity of the piece that three film versions have been made, the latest one in Japanese!
