Once again we focus on Nami Matsushima. This time she has a sister who goes missing and after getting too caught up in doing something about it, our innocent heroine is given a fifteen year sentence for a murder she didn't commit. She's sent to an all women prison where she's not exactly welcome. Her fellow inmates torture, humiliate and try to kill her; but the Scorpion prevails long enough to get some justice.
