The next day, he takes the advice of his friend and visits a fortune teller, who warns that his whole family is in great danger and may die, and advises him to fortify himself with black magic.

Tomi becomes strange and withdrawn. Rita's boyfriend, Herman, says that for 40 days after a person dies, that person's spirit will linger at the house. Shortly after that, a housekeeper arrives - Darminah, allegedly sent by an acquaintance of their father to look after the house. That night, after a party, Rita is scared when she sees a kuntilanak.

Herman says Darminah is not a good person, and offers to consult a shaman about the situation the next day. Mr. Karto also begins to notice her strange and suspicious behavior. Tomi meets with a kiai at a bookstore, who advises him to begin performing his religious prayers, but when he tries to begin, a kuntilanak appears and tells him to stop. the next day, Tomi finds Mr. Karto's corpse, hung. Later that day, Rita's boyfriend is also killed when he is run over by a truck after nearly colliding with a woman - Darminah. That night, Tomi and Rita agree that the ghosts in their home must be removed. When Rita leaves, she is chased by the now-undead Herman. The next morning, Rita and Tomi tell their father to call a shaman, who does so. The hired shaman is attacked by broken glass and flower petals. Rita, Tomi, and Munarto watch as the shaman's head is impaled and pelted by a spinning chandelier.

When everything is over, Darminah sneaks out, but Tomi follows her to the cemetery, where the sinister housekeeper meets with the now-undead Herman and Mr. Karto and then raises Mawarti, ordering her to kill her family. When they notice Tomi spying on them, they give chase, but he escapes. At home, Tomi immediately warns his father and sister about Darminah. Rita believes him, but their father does not. He takes them to check Darminah's room, but she is somehow already there.

The next day, the siblings dig up their mother's grave to confirm that her body is still there. When they return, the entire family is assaulted by the undead - Herman goes after Rita, Mr. Karto haunts Tomi, and Mawarti harasses Munarto. They escape into the dining room, only to find Darminah there holding a skull and frizzy hair. It turns out that Darminah is a demon who attacks those of weak faith. After being terrorized and dying without repentance, those people become slaves to the devil in hell.

The family runs to the front door and opens it to flee, only to discover a kiai and his supporters there to help. Together, they confront Darminah and the three zombies with the letter of the Qur'an, which sets them all on fire. The film ends with Munarto, Tomi, and Rita, all newly re-converted, returning from the mosque to their car. The camera reveals that the woman in the car next to them is Darminah.
