 Reformed ex-con Al Baldwin is unpleasantly surprised when former cell-mates Tom Wright and Frank Jennings visit his rural garage and tell him of their plan to steal $12,000 in cash from the regular farm combine shipment. When Al refuses to help, Wright s wife Delle holds Al s wife Cathy at gunpoint while the robbery takes place. The money is taken as planned, but guard Sid Wells is murdered and Sergeant Walters quickly finds the abandoned truck. He and Dan Mathews investigate and deduce that the Baldwins are in trouble when the nervous Al introduces Tom Wright as his new "helper". They lure Wright away from the house and capture him, but find that they must utilize a high-risk ruse in order to get close enough to rescue the Baldwins and capture Delle Wright and Frank Jennings.
