Samantha "Sam" is an orphaned young woman who moves to an isolated boarding house in North Jakarta, trying to avoid the advances of her pervert stepfather. The landlady of the house, Yanti, tells her that the house was previously a batik factory of Mangkoedjiwo family, with its current leader, Raden Ayu Sri Sukmarahimi Mangkoedjiwo having lent the house under a condition that the second floor is locked up with no one allowed inside. While listing other restrictions, including about a chair in front of a Javanese mirror in Sam's room, Yanti chants "durmo", a Javanese poem said to be able to summon Kuntilanak, a female ghost with half the body of a horse rumored to be living in a weeping fig in front of the house. Meanwhile, Sam mentions her recurring nightmares of a woman in a fire with a Kuntilanak to her boyfriend, Agung. Agung learns from his eccentric friend, Iwank, and his mother that the Mangkoedjiwo is long rumored to be a black magic sect maintaining a Kuntilanak, itself can only be summoned by antique objects. At the house, Sam befriends Dinda, who tells her that there are actually three other mirrors identical to the one in Sam's room: two of which are in herself and Ratih's rooms.
