Rino, a devoted married woman and dedicated teacher, works at the same school as her husband and frequently visits the home of a troubled, truant student named Shinichi, deeply concerned for his well-being. Despite repeated warnings from her husband not to get too involved, Rino ignores his advice and grows closer to Shinichi. With malicious intent, Shinichi begins spiking her tea with aphrodisiacs, slowly manipulating her body and mind to make her his. As the drugs take effect and Rino's desires become uncontrollable, she is ultimately seduced and taken by Shinichi, falling completely into his trap.
