Forced to quit his job as a doctor and flee after a `bloody bargain` with the child beggars mafia, Kemal moves with his family to his uncle`s mansion. When the dark secret he is involved in to save his little daughter Ruya from her illness combines with the darkness of his mother Lale`s mind, who has Alzheimer`s disease, the mansion they move into turns into a maze of paranormal nightmares. Meral enters the house under the pretence of helping the family, but her real intention is to fulfil the conditions of a Zulmat ritual held on the black moon.
