The class had a field trip so they went early at 3am. A kid came up to them and told them to be careful, but Erich just ignored it so a kid pretended to have his head cut off and there was a commotion And suddenly the bus lost its brakes and fell into a ravine near the forest, but they didn't know that they were accompanied by a cursed doll, a classmate of the three of them, and that's when the killing began. Will any of them be left?
