A group of teenage girls known as "Sweet Angel" make a living by drugging lecherous older men and stealing their money and valuables. Behind their illicit activities, it's revealed that Nene Tanaka, daughter of the powerful Tanaka conglomerate that influences politics and finance, is actually a key leader within the group. Nene falls into a trap set by the Black Lion Society and is taken captive. Subjected to humiliating pleasure-based torture under the guise of interrogation, the other Sweet Angel leaders force her to endure in order to preserve their pride. Her plight creates a dramatic struggle caught between strength and vulnerability.
