Silly plot,wonderful actors. This is Lehman's only claim to fame,although he was helped by Claude Autant-Lara who was to become one of the most important directors of the years to come("Douce","le diable au corps").It's not much of a plot (a fric frac=break-in),but the fabulous threesome make it a winner.Michel Simon plays a gentle thug,so lazy his nickname is "Jo with the arms cut".Arletty is Loulou ,a whore who teaches slang to the respectable Marcel ,a clerk in a jeweller's shop ,object of his two "friends' " desire.A lot of fun is guaranteed for all!
