A high-security prison island houses the most dangerous female convicts. A prison warden, wearing a pig mask, runs the facility and believes in a unique approach to rehabilitation, combining elements of Death Games and real-life board games to teach lessons and pursue romantic connections. Among the inmates is a hardened female yakuza who takes part in these unusual activities with a great deal of doubt and reluctance.
