 Steve Naylor was imprisoned for six years for his part in stealing $250,000 in an armored car robbery. The money was never recovered and an insurance investigator has been watching him and informing Dan Mathews of his movements. When the investigator informs Dan Mathews that Naylor has suddenly broken his routine, Dan and his officers know they must be discreet about following the tail-wise felon. They use an unmarked car and triangulation radio equipment (complete with concealed transmitter) to follow Naylor and his accomplice Carson to the remote hiding place. A gun battle erupts after the money has been dug up. Naylor and Carson s greed and mutual distrust for each other result in an ironic climax.
