We're No Angels (1955)

A strangler... A swindler... A safecracker... Yet you'll love them!

Three convicts escape from prison on Devil's Island just before Christmas and arrive at a nearby French colonial town. They go to the store of the Ducotels, the only store that gives supplies on credit. They initially intend to take advantage of them but have a change of heart after they find the family is in financial troubles.
