Motorcycle mechanic C.C. Ryder (super bowl champion N.Y. Jets quarterback Joe Namath) joins The Heads, an outlaw biker gang.
Fellow gang members menace fashion journalist Ann McCalley (Ann-Margret) when her limo breaks down in the desert, but C.C. comes to her rescue.
The bikers disrupt a motocross event tied in with a fashion shoot, but C.C. enters the competition under Ann’s admiring eye.
His win puts him at odds with Moon, leader of The Heads and when C.C. leaves with his cut of the prize money, the bikers kidnap Ann, and C.C. races Moon to win her freedom.
