Nami Matsushima has escaped from the prison to which she was sentenced in Scorpion, but is now obsessed with tracking down the--don't laugh--one-armed man who murdered her younger sister fifteen years ago. Nami is certainly no great action heroine, and the plot at times makes little sense, climaxing with a coincidence more ridiculous than any Shakespeare ever used. For complicated reasons, Nami uses her medical knowledge to break into a women's prison as staff physician. There, as in the previous movie, the convicts wind up naked awfully frequently.

Sendo, champion of the Osaka Expressway is challenged to a race by Tatsuya Shikiba, champion racer of the Metropolitan Expressway. During their race, Sendo crashes and injures himself. Two months later, when Sendo is released from the hospital, je looks to find Tatsuya for a rematch. Tatsuya has given up racing after the death of his friend Kazuki during a race, but Sendo wants his rematch. Kazuki’s sister, though distraught with the loss of her brother, decides to help Tatsuya get over his fear of racing and get back on the road to live out his and Kazuki’s dream of being a race car driver.
