At the start of the journey, the teenagers meet a couple of people who are also searching for loved ones who never returned from the hike. It soon turns out that the keeper of the sacred mountain, the Kuncen, died under mysterious circumstances. Locals believe that as long as Merbabu has no new keeper, its territory is defenseless against supernatural forces. Now the heroes must find a new Kuncen and save the missing before the dark entities completely seize power over the volcano.
