Ten years ago in the town of Harmony, an inexperienced coal miner caused an accident in the tunnels that trapped and killed five men and sent the only survivor, Harry Warden, into a permanent coma. But Harry Warden wanted revenge. Exactly one year later, on Valentine's Day, he woke up...and brutally murdered twenty-two people with a pickaxe before being killed. Now, after years of peace, something from Harmony's dark past has returned. Wearing a miner's mask and armed with a pickaxe, an unstoppable killer is on the loose.
