My Bloody Valentine

There's a big Valentine’s day party planned in the little mining town of Valentine's Bluff. It is the first Valentine‘s party in 20 years, because then there was an accident in the mine, and the accident happened because the men responsible for the security were at the party. The sole surviving miner killed them, and told the town NEVER to arrange a valentine party again. The party begins, and so does the killing. (official distributor synopsis)
