Songko

In the late 1980s, in the Minahasa region of Manado, Mikha (Annette Edoarda) and her entire family were forced to leave the village because Helsye (Imelda Therinne), her stepmother, was accused of being the incarnation of Songko. Songko is a black-robed supernatural figure who has long terrorized and killed many teenage girls in the village by sucking their blood. However, despite being exiled from the village, the villagers are still terrorized by Songko. Who is Songko, and what is his connection to Mikha's family?
