Sebastian goes into the shed to try to start the generator but, in the darkness, he trips over a cable on the ground, pulling down a metal shelf. He discovers a hidden niche in the wall containing a box with six female scalps inside.The scalps belong to a serial killer who killed in the area twenty-five years earlier, nicknamed "the Hairdresser" by the press. The ones found by Sebastian would be his trophies. The killer was never caught and now seems to have returned to strike.
