A group of young men dare a classmate to reach the porch of a legendary old house, said to be haunted by the thirteen victims of a family massacre. In hopes of making a viral video they arm him with a video camera to prove he was there or to capture him fleeing in terror before even reaching the house, as others have. When he doesn't return, the guys must go in to get him. Inside they discover the truth about the house, the fate of their friend and their own fate as well.
Following an end-of-term school ceremony, the American boy Bobby decides to go with his friend Akkun into the mountains outside their village, to a place perfect for a secret base. On the way they stop into a mysterious amusement park. They have fun there, but are attacked and cannot leave. Falling in with some other children who are also lost there, they fend off a number of attacks, and gradually learn the truth behind the facility. It was put there by a man named Koike as a trap for passing children. His son Takashi needs to feed on human children in order to survive. Akkun is killed, and Bobby is captured with Tokiko, a girl they have met there. She disappears, and Koike goes to work on Bobby, trying to fatten him up. Bobby manages to escape. With the help of Saruyoshi, a mysterious old hermit, and the animals of the forest, Bobby builds up his strength and returns to the facility in an attempt to save Tokiko.——IMDb
