While Paris Sleeps(1932)

Lovers, Wantons and Wastrels are Awake

To save his daughter Manon from falling into the hands of a vicious gang of pimps, convict Jacques Costard escapes from jail. Jacques' problems are twofold: he must keep Manon from being abducted into a life of prostitution, and he must also hide his true identity from the girl, who has been raised to believe that Jacques died a hero in WWI.
