Olympic skiing champion Jean-Claude Killy stars in this clever caper that combines mindboggling plot twists with heart-stopping stunt skiing, performed by Killy himself. Alpine ski instructor Christian Biton (Killy) loves a challenge, and his expensive tastes force the ultimate challenge. With his sweetheart, the wealthy Monica Scotti (Daniele Gaubert), and a down-on-his-luck American, Bob Skinner (Cliff Potts), the cagey Biton plots the near-impossible robbery of a ski lodge. A robbery that can only be accomplished with a death-defying ski run down a virgin glacier and a stunning snowmobile jump over a mountain crevasse. Despite many frightening interferences, the trio of robbers succeeds. But their success draws the attention of an insurance investigator (Vittorio De Sica), and after that, nothing is what it seems.
