Four hikers become trapped in a mysterious village after getting lost in a mountain foot market said to be an interdimensional gateway. There, the world turns strange—graveyards with no headstones, grinning bald figures, puppets with no puppeteer, and cult rituals dancing atop corpses. It all leads to one chilling truth: those who are trapped can never leave. The village is preparing a dark ritual to fill the hamlet with the dead. Faced with harrowing choices, can they survive—and make it home alive?

Sumala, a name that is feared by people in a village in Semarang Regency from the past until now. No one dares to go out when night falls because Sumala will come to kill.
