One day, the five of them were taken to visit the Jogja Art Museum which gathers various collections of history, art and musical instruments from the time of the Majapahit Kingdom, Matara Kingdom, ancient, Mataram Hindu civilization to the time of the small ancient Gong attracted the attention of these students. especially the most naughty Trisha among them. Trisha and Mira's gaze is tied to the ancient Gong of Mataram which seems to summon their spirits. When they return to their accommodation, they are shocked to find out that Trisha has stolen out a small ancient Gong. They objected as hard as Trisha's actions but it was said that the gongs could produce a rather odd sound compared to regular gongs. Furthermore, the carvings around the Gong are very strange and impressive. That night, while everyone was asleep, Trisha had startled Ika and told her of her intention to hit the gong. Trisha felt like the Gong was calling to her. Before dawn, when all of them were connecting lena, a black board had emerged from the darkness outside and soared slowly approaching the Gong which happened to be placed alongside the other gamelan instruments. From that moment on, the five of them were always faced with a creepy experience that became more and more frightening from time to time because the board would harass them regardless of place and time until they all became chaotic like there was no way out.
