Mining town Valentine Bluffs hasn’t had a Valentine’s Day dance for over twenty years — ever since the accident. Two supervisors messed up and left several miners trapped below just so they could go to that dance. They didn’t even check the methane levels, which led to the explosion that trapped the men. Only Harry Warden survived, living off the bodies of his co-workers, until he could escape and kill the supervisors. He was committed for two decades and finally forgotten. Now, the dance is back on. Someone, somehow, is going to pay.
My Bloody Valentine right when slashers were king, complete with so much gristle that nine minutes of offensive violence was removed. Just imagine — the film starts with a nude woman impaled on pickaxe, so it still got worse than that.
Even after officials decide to close down the dance, a bunch of young miners have their own party at a bar. Why would you do that when Harry Warden wants to kill everyone? This movie is packed with death, from nailguns to the face and beheadings to people being impaled on shower heads.
It’s also a giallo-esque story, with the murders in the past warping one of the characters so badly that he or she commits the murders in the present. The mystery of who this character would end up being was kept hidden even from the actors until the final scene was filmed.
Interestingly, once the producers decided to shoot in the Sydney Mines in Nova Scotia, the town cleaned the sets up so they would be more presentable. This led to a set that looked like Disneyland, according to reports. The filmmakers had to go back and make the sets look darker to fit the script. That said, because the movie was filmed in legitimate mines 900 feet underground, special lighting devices were required because of the danger of methane explosions.
