Richard Sarafian directed this minimalist chase film, starring Barry Newman as ex-marine, ex-race car driver and cop named Kowalski. He drives into Denver to deliver a car and pick up another vehicle to drive to San Francisco. To make the fifteen-hour drive to San Francisco bearable he pops a load of pep pills and drives off. Almost immediately, he is told to pull over by the police, but Kowalski refuses to stop. Ignoring the cops, a police chase ensues. Egging Kowalski on is a blind black disc jockey, Super Soul (Cleavon Little), who announces his comings and goings on his local radio show, praising Kowalski to the skies as "the last American to whom speed means freedom of the soul." Super Soul's hype makes Kowalski a media sensation and Kowalski fans mount up -- as do the police cars chasing him -- as he races against time to deliver both the car and himself to his San Francisco destination.
