A renegade trucker clashes with a redneck sheriff and the authorities in general as he leads a mammoth convoy across America. Sam Pekinpah's road movie inspired by the song by CW McCall, starring Kris Kristofferson, Ali MacGraw, Ernest Borgnine, Burt Young and Madge Sinclair.

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.
