The story starts off with a race, a race including Smoke, the King of Cali. Alongside him are the other members of his bike gang, the Black Knights, including Kid, a prospect. Kid, whose father is Smoke's mechanic/best friend, is anxious and impatient to start his life as a member of the Black Knights. He wants his father to look at him the same way he looks at Smoke. Kid's dreams are shattered, however, when Smoke's race gets out of hand and his father is hit + killed. Flash forward to a year later, where a now cocky Kid has joined forces with Stuntman. The two have been traveling California, hustling other racers out of their money. After another routine hustle, Kid runs into Smoke, and challenges him to a race. Smoke refuses, stating that Kid needs to join a gang and win some races before he'll be up to his standards. Prompted by Smoke's refusal, Kid forms his own gang -- the Biker Boyz -- with only three members, himself, Stuntman, and Primo, another free lance racer. The three set off, immediately building a following and gaining prospects. Along for the wild ride is Tina, a feisty young woman, who is drawn to Kid by is incessant devotion to her. During an annual party, Kid and Smoke are both enlightened by Kid's mother that Will, the man who raised Kid, is not his real father -- Smoke is. Smoke is shocked, but Kid couldn't be more angry. After fighting with his mother, he leaves home and moves in with Tina, determined to beat out Smoke and the Black Knights. Unable to wait for success, Kid begins hustling again, despite it being against code. After Smoke saves him from being killed by another gang in Fresno, Kid challenges him to a race, the stakes being the end of racing for both of them. The gangs travel to Fresno, where Kid races Dogg. The race ends badly and it looks as if Kid won't be able to race against Smoke the next day, seeing as his bike is totaled. Dogg, however, comes through and lends Kid his bike, with hopes that Kid will beat smoke and put an end to his reign as King of Cali. The next day, the two gangs meet up and set their terms before Kid + Smoke head off to the path they'll be racing on. The race starts normal for Kid, but Smoke has already gone in the zone, everything but the road ahead of him blurring out of vision. Suddenly, Smoke's tunnel of thought is filled with memories, of everything since the night Will was killed. During this, Kid comes into the zone, his mind focusing on nothing other than the road. As the two edge closer to the finish line, Smoke lets up, allowing Kid to beat him. As the movie ends, Kid and Smoke come to an understanding, and Kid allows Smoke to keep his helmet and his right to race.
