Hotshot street-racer Phil Sandifer is working as a truck driver when he is harassed by a sports car driving on the highway. He later meets up with the driver, Jana, in a local club. Jana challenges Phil to a race; Jana runs Phil off the road, and he loses. At the same time, his best friend Sonny is run offthe road and killed by an unidentified assailant. Later at the club, Phil is arrested for destruction of city property and trespassing in the area they raced through, reckless driving, and hit-and-run and manslaughter for Sonny's death. The hit-and-run and manslaughter charges are dropped but Phil is found guilty of the other three charges - as a result, Phil is placed on probation and is stripped of his driver's license. Phil quickly launches into an investigation into Sonny's murder, his first suspect being Jana. She denies any involvement, and joins Phil in his investigation. He follows the trail of clues to nightclub owner Sidney Chillas, and Chillas's lackey Bruce, who runs the gym Sonny used to frequent. Chillas hires Phil as a singer under the alias of "Daddy-O". Not long after being hired, Phil is beaten up by a couple of drug dealers who have mistaken him for Pete Plum, a pseudonym used by Sonny. Phil draws the conclusion that Sonny had been moving money around for Chillas, and that he had stolen some of the money and was killed as a result. Phil confronts Chillas with the information, and they confront one another in a liquor cellar. Phil manages to knock Chillas out, and soon the police arrive and arrest him and Bruce. The movie ends just as Phil is asked to sing.
The film was released by AIP on a double bill with Roadracers.
