Hit man Woody Lane is captured by Detectives Styles and Royster after killing a crime rival for Lou Gerard, owner of the Club Flora. Caught with the weapon in his hand, Woody still gets off. His lawyer proves that the gun could not possibly have fired the murder bullets, even though Sgt. Bingham's ballistics tests had proved otherwise. 

Led by Joe Collier, their former Sergeant in Korea, Joe Woolard and other veterans turn to crime. Bill Crowley and Pepper Anderson investigate when the vets steal M-16 rifles, an anti-tank gun and ammunition from a National Guard armoury, killing a guard in the process.
