Five snowboarders -- the best in their field, we're told -- are dropped off via helicopter atop an Alaskan mountain. All they have are their boards. Can they possibly make it down? Unfortunately, if you want to find out -- and rest assured, the answer is extraordinarily anticlimactic -- you have to sit through an hour and a half of uninspiring documentary about the history of snowboarding and boring flashbacks to what each of the five was doing one month prior. The setup sounds like an MTV series: Five snowboarders come together to live in a cabin in Alaska and try out some freestyles in the wild, on mountains no one has ever tried (the term "first descent" means being the first person to board down a mountain). If the goal was to do the Dogtown and Z-Boys of snowboarding, the movie needed to be centered on some of the pioneers, or at least on some of those who brought the sport mainstream.
