When Cooper, who is now 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. Their 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 punishing Rocky Mountain winter, fighting for both their relationship and their lives.
