Freeriders

The subjects of this thrilling documentary, who definitely put the word "extreme" into "extreme skiing," prove that the quest for the next great adrenaline high knows no national boundaries. In countries ranging from Norway to Chile, wherever there's snow, skiers rush headlong and fearlessly down mountainous slopes, at speeds eclipsing 100 mph in some cases -- fast enough that one small mistake could be a daredevil's last. Meanwhile, others catch "big air" in a gravity-defying sky dance.
