A male student confesses to his homeroom teacher who is a shut-in. Naturally, she rejects him and scolds him for his sudden visit. The student, harboring resentment, brings along his delinquent friends and breaks into her home. Since they are students and not physically strong, they all gang-rape the teacher. The teacher, unable to resist after being violated, is used daily as an outlet for their pent-up sexual desires, forced to engage in sexual acts at her own home.
