An abnormal desire from her father-in-law leads to the collapse of a happy family. A full-term pregnant woman, on the verge of childbirth, is tormented by her father-in-law's evil desires, descending into a hell of pleasure. In this extreme situation, she is sequentially violated by both father-in-law and son. The virtuous wife is consumed by their lust. The grandfather possesses an innate deviant libido, molesting not only his son and grandson but also his daughter-in-law's pregnant body. This chain of pleasure completely destroys the family. The father-in-law's words, "This time, you'll get pregnant with my sperm!" mark the beginning of terror and tragedy.
