Build a movie plot around this: How many supervisors left the miners in the mines to attend the dance not stated
Two miners in full gear, including face masks, are seen going down into a deep mine shaft, each carrying a pick axe. They reach an alcove and one of the figures takes off the mask, revealing that she is a young woman. She removes part of her uniform and stands in a state of half-undress in front of the other figure, presumably a man, who does not remove the breathing mask that covers his head.

The accident was due to the negligence of two supervisors who were anxious to get to the Valentine's dance, having left their posts while the men were still below - and having failed to check for dangerous levels of methane gas. Of the five men who were trapped in the explosion, four of them died. A survivor named Harry Warden was rescued, found in a state of mental collapse; the rescue took so long that Harry had resorted to cannibalism to survive, eating the bodies of his dead coworkers. Harry took revenge on the two supervisors, attacking them with a pick axe and tearing out their hearts, leaving them in decorative Valentine boxes and warning the town to never hold another Valentine's dance.The warning had been heeded until now, and the town tries to put the past behind it by having another dance. The younger people of the town are excited...
