As a massive winter storm bears down on Wyoming, recluse Arlo Griffith and his faithful dog, Monkey are headed home to hunker down. But on the way, he takes in a young couple who have broken down in the path of the approaching blizzard. Heather and Hayden are half his age, twice as crazy and nothing but trouble. Trapped in Griff’s shell of a home, the onslaught of chaos, sex, drugs, alcohol, snow and tacos may cost Griff his sanity. Or maybe even his life.
