Factory owner Maryati exploits her employees with excessively long shifts, luring them with incentives to make them prioritise productivity and greed over sleep. Putri is convinced that, because of this, her mother, who worked in the factory, committed suicide. Her sister Ida, however, believes that their mother died from being possessed. She thinks that whenever the workers grow weak from exhaustion, a dark and evil figure emerges and takes possession of their bodies. To prove her theory, Ida decides to work day and night in the factory so that she, too, will become possessed and can see for herself the being that she believes seized their mother’s body. The sisters have a younger brother, Bona, who was born with a special gift that enables his wounds to heal quickly whenever he is injured. As the sisters investigate their mother’s death, a ghostly figure searching for an ideal body seeks to take advantage of Bona’s gift, putting him in danger. The three siblings now must bravely confront their own weaknesses and find strength in their faith in each other to overcome the terror that threatens their family.
