Endah, Fadhil, Dwi, Hendra, Wati, Ningsih, and Franky set off with dozens of others to a sugar factory to become seasonal laborers. Every year, the sugar factory hires people from the surrounding villages to speed up the sugarcane milling process during the harvest season. At first, everything went normally without any oddities, until one night, Endah woke up and left the dormitory where she was staying to follow a mysterious figure. Since that night, the workers began to experience escalating terror, starting from a workplace accident that befell one of them, to the gruesome death of a worker in the back well. Then it was revealed that the factory was adjacent to the demon kingdom, something had made the demons angry, and now they were demanding the lives of the workers.
