Plot summary

Three truckers are setting off across country when they are harassed by a local Sheriff. The Sheriff is happy to use his power to extort money from anyone who he runs into, and he has a particular dislike for truckers. He and one of the truckers, "Rubber Duck", have a long-standing feud. This boils over when the truckers refuse to give in to one of his extortion attempts and get into a fight with the Sheriff and the local police. This results in a cross-state, even inter-state chase, and grows in magnitude as more and more trucks join the rebels, forming a convoy.—grantss
