Dwayne McLaren (Liam Hemsworth ) a high school star athlete recently turned auto mechanic, dreams of getting out of tiny Cut Bank, MT, the coldest town in America, and whisking his pageant-hopeful girlfriend, Cassandra (Teresa Palmer), away to the big city. But his plan to do so sets in motion a deadly series of events and thrusts him into a police investigation headed by Sheriff Vogel (John Malkovich), the protector of Cut Bank and the closest thing Dwayne has to a father figure. Panic sweeps across the community in mere hours, but things are not what they seem. Cassandra's father Big Stan Steeley (Billy Bob Thornton) is the only one who seems to realize this. However, the damage is already done and the events that unfold change Dwayne's life, and the life of the town, forever.
