The expert karate skills never stop when Kevin Ryan, played by Ted Jan Roberts, a 13-Year-Old - Black Belt Martial Artist, and his very pretty sister Shonda Wipple, go to California to visit their Uncle Bob, Stephen Furst. They soon discover that Uncle Bob is a fast-talking, heavy-gambling, second-rate alcoholic movie agent, who owes big bucks to Mob Boss, Joseph Campanella. Kevin and his entourage lead the bumbling bad guys on a high-speed comedy/action chase throughout the city of Los Angeles. When all seems lost, he is rescued by his idol, holder of Ten World Kickboxing Titles, Don "The Dragon" Wilson, making all of Kevin's dreams come true.
