Pepe, a young Chicano, is put down as a "loser" by Riff and his friends. In order to humiliate Pepe, Riff challenges Pepe to compete in the local dirt bike races. Pepe reluctantly agrees, although he knows Riff is the champion. Pepe takes an extra paper route in order to buy a better bike, practices long hours to perfect his skills, and at last the big day arrives. As the racers near the finish line, Pepe is in the lead when a sudden accident places Riff in danger of serious injury unless he gets help fast. Pepe must choose between winning the race or helping Riff.
