A man lives with his family in a quiet residential neighborhood. He has been living separately from his wife for several years, while his son remains shut away in his room. Unrecognized and isolated at work, he endures each day in loneliness. His only pleasure is secretly luring a high school girl into his room, locking her inside, and raising her according to his own desires. Subjecting her to hunger, fear, intimidation, and verbal abuse, he psychologically breaks her down. Eventually, he bends her completely to his will, using her continuously as a sexual object—an abnormal indulgence through which he seeks to soothe his profound loneliness.
