Robert M. Sherman

When vigilante land baron David Braxton hangs one of the best friends of cattle rustler Tom Logan, Logan's gang decides to get even by purchasing a small farm next to Braxton's ranch. From there the rustlers begin stealing horses, using the farm as a front for their operation. Determined to stop the thefts at any cost, Braxton retains the services of eccentric sharpshooter Robert E. Lee Clayton, who begins ruthlessly taking down Logan's gang.

Trucker Rubber Duck and his buddies Pig Pen, Widow Woman and Spider Mike use their CB radios to warn one another of the presence of cops. But conniving Sheriff Wallace is hip to the truckers' tactics, and begins tricking the drivers through his own CB broadcasts. Facing constant harassment from the law, Rubber Duck and his pals use their radios to coordinate a vast convoy and rule the road.
