One day, a mysterious stranger arrives in town riding an extraordinary motorcycle. Shortly thereafter, a sleek and enigmatic black car also appears, challenging the gang's control over the local roads. The leader of the gang, Packard, has a notorious reputation for forcing people into street races which usually end in devastation for his opponents. The gang's reign of terror includes the murder of Jamie Hankins, a local youth, who had been dating Keri Johnson, Packard's reluctant girlfriend. With Stingray Street Racing as their base of operations, Packard and his crew wreak havoc, unchecked by local law enforcement.

Each encounter leaves a scorched mark, and it becomes clear that this avenger is not merely human. The mysterious stranger befriends Keri and befuddles Packard with cool defiance. The newcomer creates alliances with local teen Billy Hankins, Jamie's younger brother, who struggles with his brother's unsolved murder. As alliances form and tensions mount, events lead to confrontations that blur the lines between life and death. Loyalties are tested and fear grips the gang as they realize that this unknown avenger possesses abilities beyond comprehension, threatening to destroy their reign forever.
