Some bikers are hired by the CIA during the Vietnam War to rescue a captured agent from the clutches of the Red Chinese army. After a round of drinking, fighting, and whoring around, the cycle gang, led by Big Bill Smith, fix up their Yamahas with machine guns, grenades and armor plating, and storm the enemy camp.

Angel (William Smith), an outlaw biker, sells out his gang by exposing their wild conquests to Like magazine for $10,000. With his photo on the cover, Angel skips town and tries to start over with help from sheep rancher Dan Felton (Dan Kemp). An ex-motorcycle enthusiast, Dan becomes a mentor to Angel, giving him hope for a peaceful future. But Angel must put hope aside when members of his former gang viciously attack Dan's teenage daughter.
