Mari Rika slips into a skintight black suit and takes on a criminal organization in this full-scale undercover-agent thriller. Guest star Hamasaki Mao joins her for an intense lesbian scene between female agents. Rika is captured, raped by the enemy, locked in a cage and kept drugged. She is tormented by tentacle nightmares and subjected to electric-shock torture. This commemorative release was also the final production filmed at the famous abandoned-building studio.
