Jack Caffery comes face to face with absolute evil. Who will emerge victorious? The discharge process is followed to the letter when a patient, Isaac, is released from the high-security psychiatric clinic. But something is wrong... Very wrong...

Inmates and staff are haunted by the legend of Maud, a ghost rumored to have abused children in 1860. They believe she has returned and is responsible for the self-harm and death of a patient, as well as a series of unexplained incidents.

However, they will soon realize that the ghost is not what they should be worried about. The patient they just let go is likely connected to the unexplained incidents. He should not have been released. Terrified, they will inform Detective Jack Caffery. He must find him very soon, before he kills again. Could the answer lie in the terrifying little dolls Isaac made in the psychiatric ward? Do they hold the clues that will bring Caffery one step ahead of the psychopathic killer?
