Ah, just yesterday this was still a peaceful household... While their father was away on a business trip overseas, the son hatched a devilish plan—an unnatural scheme to tame his nagging mother like a domestic animal. Watching his unsuspecting mother live her ordinary life, the son lay hidden in the closet, waiting. Suddenly, he pounced as she carelessly remained naked in the bedroom. He probed the very womb that bore him and assaulted her violently. The mother endured the abuse, yet could not suppress the perverse pleasure she began to feel. But this was merely the beginning of his plan. To instill fear, the son wielded words as weapons, repeatedly threatening, "Mom, if you don't obey me perfectly, I'll kill you." Now, a terrifying relationship hidden within the family home begins to unfold.
