The Prison

Keller is a decorated ex-Army Ranger who is sent to a remote snowbound prison for breaking into a car owned by a senior FBI Agent. The prison is run by corrupt Assistant Governor Andrews and brutal head guard Johnson, who are running an illegal fight club with a select group of prisoners. Keller falls foul of Johnson and is recruited to the fight club, where he encounters Dr. Colmy, the prison doctor, and nurse Trace. Colmy is an amateur palaeontologist who is exploring a huge cavern beneath the prison. The cavern is covered in ancient wall paintings that tell the story of the original ice-age dwellers who were hunted by a fierce creature. Colmy believes that the creature is still alive and embedded in the ice, and he is determined to find it. Keller also learns that the violence of the fight nights is feeding the creature, enough to allow its spirit to take form as it wanders the corridors of the prison at night. Keller confides in Trace that he has been placed there under cover to gather evidence of criminal activity. He asks her to hack into Colmy's laptop, but she doesn't believe him. Keller then approaches the Governor himself, who knows nothing of the activities of Andrews and Johnson. He asks the Governor to contact his FBI Controller. At the same time, auditors are visiting the prison and, finding evidence of dangerous and illegal practises, confront the Governor, threatening to have the prison shut down. The Governor freaks out and asks Andrews for help. Keller is taken to a private cell by two guards and waterboarded to find out what he knows. Trace has relented and broken into Colmy's laptop, but she is discovered and dragged down to the cavern where she is forced to watch while Colmy begins to drill into a frozen waterfall where he has found the frozen remains of the Horned God. Up above, a riot has broken out at the fight club – shots are fired, people are being killed. Keller returns to the Governor's office where the Governor has armed himself, determined to save his prison. He tries to shoot Keller but Keller kills the Governor, arms himself and heads back into the prison. Andrews is now in his office, destroying evidence – he piles files on the floor, pours petrol over them and sets fire to them. He next goes to the generator room and opens the fuel taps, intent on burning the whole place to the ground. In the cavern, the blood and violence from overhead has awakened the Horned God and as it kills Colmy, Trace escapes and makes it back to the prison where she runs into Keller. As fire begins to spread they escape the prison just as the fuel in the generator room ignites and the place blows up. Keller and Trace are alone in the snow, making their escape. In the final scene, the Horned God appears and laughs.
