Plot

On Valentine's Day 1997, six miners are trapped underground by an explosion at the Hanniger mine in the small mining community of Harmony. By the time rescuers reach the miners, they find only comatose Harry Warden still alive. Further investigation reveals that Warden killed the other miners to conserve oxygen. Tom Hanniger, son of the mine's owner, is blamed for the explosion as he forgot to vent the methane lines that caused the collapse.
