Carter Wong, Angela Mao and Anne Winton have to now try and rescue him. This leads to an explosive climax with the heroes having to fight the likes of Wong In Sik, Sammo Hung and Kenji Kazama.
Background
Rhee landed the role in the film with help from his friend Bruce Lee whom he met in 1964 while both were performing demonstrations at an international karate event held in Long Beach, California. In 1972, Lee went to Golden Harvest Films boss Raymond Chow with the idea of making a movie about Taekwondo with Rhee in lead role. Rhee who never thought of himself as an actor didn't think it would come to fruition but a year later in the summer of 1973, Rhee was flying to Hong Kong to star in the film which was set in Korea, playing the part of Master Lee, a leader of a group of underground patriots. The plot for the film was based on a synopsis written by Rhee. It didn't take long to produce the film and by July 19th Rhee was back in the United States. This was when Bruce Lee called him to let him know that the film's editing had been done and it was ready for release. Rhee was looking at the possibility of more film work but with Lee's death which was around the film's release and the possibility of being away from his family didn't appeal to him. So this became his first and last film. This was the first film for Rhee. It was also the first film for Anne Winton, a 23‐year‐old student from Washington. An article in the Lowell Sun suggested that Winton's role, with her as a blondeAmerican girl in the film along with some other new approaches may have also been for international appeal and profit. Winton who had studied ballet at the University of Michigan came to Washington in the early 1970s. Later she attained a black belt in Taekwondo. Playing the part of Mary, the niece of the Catholic priest Father Louis, she, according to reviewer World Film Geek held her own quite well in the role. Far East Films in its review said she was surprisingly both powerful in fighting ability and acting. Winton met an untimely end in October, 1982 when her husband and father of their five year old son stabbed her and their son to death before killing himself.
