A story depicting the twisted daily life of a household of three: a kind and well-behaved older sister, a quiet younger brother who always obediently follows, and a perverted father with a deeply disturbed personality. The sister always speaks to her father in polite language, silently complying with any lewd demand he makes. The father's depraved behavior repeats itself in everyday settings—bathrooms, dining tables, and every corner of their home. Worried about his sister, the younger brother is too terrified of their father to intervene, left with no choice but to watch in silence. Once again today, the sister's voluptuous body is violated... This film reveals the disturbing, routine acts of perversion hidden within the family's twisted domestic life.
