Humphrey Bogart plays one of his rare comedy roles in this jaunty excursion about three convicts - Joseph (Bogart), Albert (Aldo Ray) and Jules (Peter Ustinov) - who are plotting their escape from Devil's Island. Fate intervenes when they hide out with kindly, but inept Felix Ducotel (Leo G. Carrol) and his family. Felix manages a store for his arrogant cousin Andre (Basil Rathbone), who makes the fatal mistake of stealing Albert's beloved pet, a poisonous snake! For the Ducotel's, it will be a Christmas to remember - shared with a trio of rogues who turn out to be three "wise men' after all!
