Baker is an ex-con who gets a job as a truck driver and discovers a racket run by top driver McGoohan and manager Hartnell. They are carrying five more drivers on the payroll than there really are, and Hartnell has the other drivers make runs for the phantom drivers and splits their pay
with McGoohan. After Baker's Italian friend is killed by the two, he sets out to put an end to the scam. McGoohan and Hartnell are killed when their truck goes over the edge of the quarry during the chase. A worthwhile thriller.
