We're No Angels: In Christmas, three prisoners - Joseph, Albert and Jules - escape from the Devil Island to a French small coastal town. They decide to robber a store, to get some money and clothes and travel by ship to another place. They pretend to be there to fix the roof, but pretty soon they realize that the financial condition of the family Ducotel is not good. Andre Tochard, the selfish and mean owner of the establishment, explores the family Ducotel. The three convicts spend the Christmas night with the Ducotel and are so well treated by the family that they decide to help them. Their pet will help them to fix the situation.
