"Jealous" man-killer Mayumi (Hitomi Kozue) is sent back into solitary confinement after being re-arrested for the murder of the doctor who fingered her for a botched surgery. After emerging from solitary confinement to find an all-new gang of bullies picking on a meek, young female prisoner, Mayumi is now a much harder soul who takes no attitude from anyone, and she turns savage when the poor girl is enslaved by Yakuza.
