Obviously these gangsters are the bad guys Dragon Lee is looking for and he soon links up with Silver Snake and helps battle the gangsters, leading to an extremely long final showdown in a holiday resort.
The film is a shameless Bruceploitation film with Dragon copying many of Bruce's mannerisms and even a Game of Death style yellow outfit. However, there is also a lot of innovation and interspersing the fighting with comedy skits and stunts, some of them very bizarre. The film is unintentionally hilarious with the terrible dubbing, at times it seems like a parody but is highly entertaining.
