Used-car salesman Rudy Russo (Kurt Russell) needs money to run for State Senate. His boss, Luke (Jack Warden), loans him the cash, but then falls victim to an "accident" orchestrated by his brother Roy, who runs the car lot across the street and is scheming to take over Luke's shop. After Luke disappears, it's all-out war between the competing car shops, as Rudy and his friends fight to keep Roy from taking Luke's property.
