Synopsis: Before the death penalty was abolished in the Netherlands in 1860, convicted killers were used in mines as so-called fire-men. They had to detect dangerous gas leaks and then set them off. Andries Martiens was one of those men and his spirit lives on and wants to kill again. Kristel Lodema and a group of her friends enter this mine where her father was doing research on these fire-men before he was killed. Unknown to them, their presence is about to unleash a night of mayhem and murder. Tonight will be Slaughter Night.
