I is for Ingrown

A man has his wife bound and gagged in his bathtub. As she struggles to break free, the man injects her with motor oil, which causes her to scratch herself violently. She bleeds and then vomits before lying lifelessly in the tub. As the scene goes on, a female voice: the woman in the tub, narrates in Spanish a monologue about how her husband's abuse just makes him a "primal" animal and not any more of a man, the monologue is directed at him.
