A group of deviant sects who worship the figure of Kanjeng Devil.

Two years without receiving news from her older brother who is studying at another city, Tia receives constant promptings to find her older brother or her father, Yusuf, will die. Armed with a photo, Tia's search leads her to a mysterious boarding house near her brother's campus. Welcomed by the couple who own the boarding house, Rosa and Jefri, Tia suspects that something is wrong with Rosa's excessive friendliness. Not to mention the presence of a mysterious young man named Nathan who keeps warning her to leave the boarding house immediately. Inside the boarding house, strange events occur in succession. The deeper Tia searches for her brother, the greater the terror she faces. Behind it all is a curse and a cult that targets Tia.
