At a seemingly abandoned farmhouse, an inexperienced woman detective trips a booby-trap wire and is killed instantly. At a secluded house in a german forest, an international criminal is arrested while found in a very compromising position with three prostitutes. On a London roof-top, a British Policeman enters into a blood oath with a Mafia capo.
These three unrelated incidents will soon plunge three policemen from three different countries into the center of the most audacious drug-smuggling operation ever attempted. Their hunt will take them from Hitler's infamous Eagle's Nest retreat in the Bavarian Alps to the halls of power in their respective departments. But when they discover the secret of the Snowman, they will be plunged into far more dangerous territory. They will each be forced to come face-to-face with their pasts - where secrets have long ago become nightmares, soon to explode into reality.
