Mittenwald, end of the war 1945: Fleeing Wehrmacht soldiers, refugees from the East, and released concentration camp inmates flood into the town, while American tanks roll in. Tons of gold and foreign currency from the Berlin Reichsbank are buried in the mountains above Walchensee: the Nazi gold. Shortly thereafter, the Americans empty the pits. A year later, the former commander of the mountain troops barracks and now operator of the American amusement club "Crazy Horse" is murdered. Commissioner Gropper, who wants to solve not only this murder in Mittenwald but also find his first love Wilma, encounters further mysterious deaths during his investigations, putting himself in great danger.
