Scorpion: Double Venom 2

Directed by Ryōji Shinmura

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.
