Ten years ago, a tragedy changed the town of Harmony forever. Tom Hanniger, 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.
This movie contains 33 potentially triggering events.
without any spoilers as possibly one of the main characters out of the around 5 of them is shown at the end of the movie to have D.I.D/a split personality
kinda, whenever tom is in town and encounters men who dislike him strongly, the first thing that happens is he gets punched in the face without warning, this happens at least twice
MAJOR SPOILER: Tom Hanniger (Jensen Ackles) is a person suffering from mental health issues due to having survived a killer's attack in a mine. Ten years later he returns. The attacks start happening again, and people think it's the original killer who it turns out actually died 10 years previously. It's discovered that Tom spent 7 years in a mental institution after being suspected of doing the crimes. Tom "turned into" the killer for unknown reasons and appears to be suffering from PTSD and DID. He violently kills a lot of people.
In one scene Tom Hanniger is shoved and called a "Cocksucker" by an older man. The character is presumably straight and this 'insult' comes out of nowhere.
