In a small village snuggled in the snow-shrouded French Alps, the son of a long-dead, high-ranking Nazi who had terrorized the area during the war, Adolph Streicher, vanishes on the ice-slick slopes. Robert Holmes, a vacationing American journalist and mountain climber, tries to unravel the son's disappearance. Instead, he becomes ensnared in a desperate and deadly plot, sparked by the arrival of one man—Walter Streicher, twin brother of the notorious Nazi. Or is he Adolph? The mystery soon explodes into bloodshed and a desperate chase across the blizzard-swept Alpine peaks.
