Escape from San Quentin is a 1957 American film noir crime film produced by Sam Katzman, directed by Fred F. Sears, and starring Johnny Desmond, Merry Anders and Richard Devon.

His sentence doesn't have long to go, but when fellow convict Roy Gruber plans a breakout and wants pilot Gilbert to help steal a plane and fly them out of the country, splitting $120,000 in stolen money Gruber has hidden, Gilbert goes along, having heard his wife Georgie wants a divorce.

The plane only holds two passengers, so Gruber roughly throws Hap to the ground, injuring him.

Low on fuel, the plane can make it only as far as a rural road where Gruber knocks a man unconscious and steals his truck.

He saves a Mexican policeman's life in the process, which law authorities say they will take into consideration as they return Mike to jail, with Robbie promising to wait for him.
