Three San Quentin escapees (Penny, Hastings and Morgan) kill a cop in a gas-station holdup. Wounded, Morgan flees through black-shadowed streets to the handiest refuge: with former cellmate Steve Lacey, who's paroled, with a new life and lovely wife, and can't afford to be caught associating with old cronies. But homicide detective Sims wants to use Steve to help him catch Penny and Hastings, who in turn extort his help in a bank job. Is there no way out for Steve? Written by Rod Crawford e4e
