A group of criminals rob a warehouse where they cosh the elderly night watchman. The watchman's ex-G.I. son Frank finds his barely conscious father who soon dies from the injury; his last words being that the group drove a white T-Bird. Frank tracks the gang down with the idea of vengeance, but the police apprehend him and force him into getting his revenge by infiltrating the gang of robbin' hoods.
