Escape From San Quentin (1957, U.S.A.)

Singing star Johnny Desmond goes dramatic in the low-budget Escape From San Quentin. Desmond plays escaped convict Mike Gilbert, who goes on the lam with fellow prisoners Gruber Richard Devon and Graham Roy Engel. While hiding from the law, Gilbert comes to realize that he’s fallen in love with Robbie Merry Anders, the sister of his ex-wife Peggy Maley. Through Robbie’s influence, Gilbert decides to go straight, but his cohorts aren’t quite so willing to reform. Like most Sam Katzman quickies of the era, Escape from San Quentin was loosely based on a true story.
