Convoy (DVD)

Martin ‘Rubber Duck’ Penwald (Kris Kristofferson, Vigilante Force) who, in pursuance of a feud with Sheriff Lyle ‘Cottonmouth’ Wallace (Ernest Borgnine, Marty), unites scores of his fellow-drivers via Citizen Band radio into a gigantic mile-long convoy which, powered by pent-up frustrations and resentments as much as by diesel-fuel, rolls irresistibly along the Arizona highways towards the freedom of the Mexican border.
