Sister Street Fighter

When Lee Long (Hiroshi Miyauchi), a shorinji kempo champion and Hong Kong drug agent, goes missing during an investigation into the activities of a dummy corporation called Central Export, his sister, Tina (Sue Shiomi), is called in to continue the investigation in his place. On her way to Club Mandarin, she visits her uncle (Harry Kondo), who operates a restaurant, and her cousins Jerry (Tatsuya Nanjo) and Remi (Nami Tachibana). At Club Mandarin, she receives a red rose, the signal to look for Lee's partner in the investigation, Fanny Singer (Xiè Xiù-Róng). When assassins for Central Export abduct Fanny, Tina takes them on singlehandedly, but they manage to capture Fanny and load her in their car, which is then hijacked by shorinji kempo student Sonny Hibachi (Sonny Chiba), who proceeds to transport her to the ballet studio operated by his girlfriend, Shinobu Kojo (Sanae Ohori).
