 George Roker robs merchants at gunpoint and his wife Lorna poses as a customer who flags down their accomplice Ed Beale immediately after Roker flees the scene. Beale impersonates a uniformed Highway Patrol officer and convinces the victims that they need not do anything further. Flush with success, they continue pulling jobs even after Dan Mathews and his officers have notified area merchants about their modus operandi. When one victim calls the Patrol immediately after the three have fled, Dan is able to determine the direction of their flight and he tracks them to a remote area. He and his officers then block the only road that would permit the felons  escape.
