On the heels of a massive sufferfest on Mt. Stimson in Montana, Cody Townsend and cinematographer Bjarne Salen hurry down to Idaho to catch a favorable avalanche and weather cycle to attempt Castle Peak, a line deep in the Idaho wilderness north of Sun Valley. Armed with a borrowed snowmobile, enough equipment to survive a week in the woods, some bad beta, and the desire to check the line of the list, Bjarne and Cody go out on a mission filled with good vibes, great laughs and some damn fun turns.
