Male chauvinist Ah Wai often boasts of his wife's submission to him. He even persuades her to pretend to be obedient in the presence of his friends who are impressed. This leads to a separation when his wife's older spinster sister comes to know of it. Despondent, he moves to an old house only to find that it is haunted. The ghost and he become friends after much hassle, but when the ghost falls in love with Ah Wai's wife, believing her to be the spinster sister, a battle of life and death follows.
