1945: a lost German bomber crashes on the Vatnajökull glacier in Iceland. Inexplicably, in the midst of World War Two, there are both German and American officers on board. One of the senior German officers claims that their best chance of survival is to try to walk to the nearest farm and sets off, a briefcase handcuffed to his wrist.
1999, mid-winter, and the US Army is secretively trying to remove an aeroplane from the Vatnajökull glacier. By coincidence two young Icelanders become involved ? but will pay with their lives. Before they are captured, one of the two contacts his sister, Kristin, who will not rest until she discovers the truth of her brother?s fate. Her pursuit puts her in great danger, leading her on a long and hazardous journey in search of the key to the riddle about Operation Napoleon.
