Eleven years ago, a cave-in on the north side of a mine trapped five miners. Six weeks later when rescue teams arrived, they found four dead miners and Harry Warden (Richard John Walters) who survived by killing the other miners with a pick-axe, and is in a coma. Tom Hanniger (Jensen Ackles) is under suspicion to have committed the crime. Finally he is blamed for the mine disaster because he forgot to vent the methane lines.
The following year on Valentine’s Day, Warden wakes up from his coma, killing many in the process. At the abandoned mineshaft that was the site of the disaster, a party is in full swing, attended by many teens, including Axel (Kerr Smith), his girlfriend Irene (Betsy Rue), Tom Hanniger, and his girlfriend, Sarah (Jaime King). Sarah goes in alone and gets lost looking for Axel and Irene. She runs across a teen and a few seconds later he is stabbed in the back of his head through his eye. She is confronted by Harry Warden in full miner’s garb, carrying a bloody pick-axe, and flees for safety; Axel grabs her and they hide from the killer. He also kills someone with a shovel by cutting her head off in half via the jaw (although she survives for a tiny while until he pushes it in harder). He eventually sees them, and they run out of the mine, where they run into Tom coming in. The killer hits him with the pick axe, injuring him, while the other three run for the car and leave him behind. Tom runs back into the mine in an attempt to get away from the killer; just as he’s about to be killed, the police arrive and shoot the killer, but he makes his getaway back into the mine.
Next, the current mine manager and Megan are killed by Warden. Tom picks Sarah up to take her to Axel’s love nest to convince her that Axel is the killer. Axel then calls her and tells her that Tom is the killer. She crashes Tom’s car and makes her way to Axel’s shack. Sarah is chased by the killer all the way to the mine. There, Sarah goes into the shaft where the original murders took place, where she is joined by both Tom and Axel, and after a brief stand off, Axel and Sarah realize that Tom is delusional. A montage then plays out all the murders in the film again; this time showing the aftermath and beforehand, revealing Tom to be the killer. The killing in the mine in which Tom was locked in the cage, is played out again, this time showing Tom commit the murder, then lock himself in the cage; revealing Warden locking him in to be a hallucination. Sarah shoots a tank and causes an explosion, and subsequently a partial cave-in. She and Axel escape, believing and reporting Tom to be dead. A rescue team comes in to the mine to look for survivors, but Tom kills one of the rescuers and escapes the scene dressed in the rescue worker’s clothing.
