Crime Wave plot
"Before your shocked eyes -- the city blasted SIN-SIDE OUT!"
Three escapees from San Quentin (Penny, Hastings and Morgan) kill a cop during a robbery at a gas station. An injured Morgan flees through the dark streets to an obvious refuge: with former cellmate Steve Lavey. Steve has been paroled and now has a new life and a devoted wife who cannot afford to be associated with his former escaped cellmates. But Homicide Inspector Sims, with the help of Steve, plans to capture Penny and Hastings, who blackmail Steve again with his help in a bank robbery. Is there no way out for Steve?
