A reunion in the wilderness between a roughneck father and his estranged son takes a dangerous turn. Billy Underwood hasnt seen his father for most of his life, until the hardscrabble Clay Underwood shows up and whisks the puzzled boy away, bent on taking him on an autumn elk hunt in the Montana wilderness. While wary of his dad and inexperienced in the field, Billy is excited, and quickly responds to Clays awkward and tough but tender attempt to bond with him through the vehicle of a grand outdoor adventure in the Rocky Mountains. As winter in the high country approaches, father and son bond in quiet, unexpected, and profound ways, while searching for and tracking the elusive elk. Clay doesnt always have the right words to express his feelings, but passes important lessons to his son, from how to track elk and predict the weather, to talking with girls and falling in love. As the prospect of finding elk grows slimmer, the weather takes a sudden turn for the worst. The dangers of being lost and alone in the wilderness quickly become apparent to father and son on a trip that inexorably hurtles toward tragedy.
