MY BLOODY VALENTINE (1981)
Valentine's Day is coming around and the young people of the small mining town of Valentine's BLuffs are organising a party. A few decades earlier an explosion at the mine trapped six miners underground. One, Harry Warden, survived, though in a deranged state. Warden is sent to a mental hospital but escapes and murders those he deems responsible for the mine accident. Now people are being brutally murdered again, and the townsfolk suspect that it is the work of Harry Warden.

MY BLOODY VALENTINE (2009)
Ten years ago, an inexperienced coal miner named Tom Hanniger caused an accident that killed five men and put a sixth, Harry Warden, into a coma. A year later, on Valentine's Day, Harry woke up and murdered 22 people with a pickaxe before dying. Now Tom has returned home, still haunted by the past. And something else is back in Harmony: a pickaxe-wielding killer in a miner's mask, who may be the ghost of Harry, come to claim Tom and his friends.
