After being used and betrayed by the detective she had fallen in love with, young Matsu is sent to a female prison full of sadistic guards and disobedient prisoners.
Once again on the lam, Matsu is helped by a strip club worker who holds a grudge against the detective who's trying to find her.
After spending a year in solitary confinement, Matsu escapes from prison with six more convicts, followed by the guards who are led by a vengeful warden who wants her dead at all costs.
