A cave-in on the north side of a mine owned and operated by Hanniger Mining Co. trapped six miners. When rescue teams arrived, they found five dead—killed by a pick axe—and one, Harry Warden (Richard John Walters), in a coma. The local papers accused Warden of killing the other five to prolong his air supply; the boss’ son, Tom Hanniger (Jensen Ackles) is questioned but released. He is blamed for the mine disaster because he forgot to vent the methane lines.

Next year on Valentine’s Day, Warden awakes from his coma and escapes the hospital, killing everyone there 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). Tom doesn’t want to go into the mine, and says he’s going back for the beer out of the car. Sarah goes in alone. Sarah gets lost looking for Axel and Irene until she is confronted by Harry Warden in full miner’s garb, carrying a pick-axe, and flees for safety; Axel grabs her and they hide from the killer. He eventually sees them, and they run out of the mine, where they run into Tom. 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; the police arrive and shoot the killer as he makes his getaway back into the mine.

Ten years later, Tom returns to town to sell the mine. Axel is now sheriff and married to Sarah. Irene is murdered at the motel where Tom is staying, then a miner is murdered in the mineshaft where Warden was chased by the cops. Axel asks his father, the retired sheriff, what happened to Warden. He says that he and Tom’s father killed and buried him. Axel, Tom, Sarah and Axel’s father go to the spot where Warden was buried to see that his body is no longer there.

Next, the current mine manager and Axel’s mistress are killed. 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 and sees himself as Warden. Sarah shoots Tom in the abdomen, and the bullet goes straight through him and into a methane tank, causing a fireball to knock down Tom. She escapes with Axel. A rescue team comes in to the mine to help Tom, but Tom kills one of the rescuers and escapes the scene dressed as one.
