When Cooper, a big city lawyer, returns home to a small northern town for his mother’s wedding, he plans to be in and out without a scratch. But his deadbeat brother, Toph, has other ideas. He coerces Coop into driving to the remote alpine cabin where they spent their childhood summers to look for their father who has gone missing. Their sketchy plan goes from bad to worse, as bruised egos and buried resentments bubble to the surface. Cars explode, cabins burn, pot cookies are consumed, and when the smoke clears, the brothers find themselves stranded in the harsh Rocky Mountain winter, fighting for both their relationship and their lives.
