1936. Germany and Japan sign a treaty with two oil companies: The two countries divide among each other the oil exploitation in Siberia. In exchange, they renounce all interests in oil in most other parts of the world in favor of these companies. The diplomatic courier carrying the German version of the treaty from Tokyo to Berlin disappears traveling on the Trans-Siberian Railroad while crossing the Soviet Union. 2002. Nearly seventy years later. Jack Boulder, a Canadian living in the Swiss city of Basel, is asked to trace the original copy of the treaty by the German Foreign Office. What is so important about an agreement that is outdated? Soon Boulder realizes that certain parts of the puzzle are not foreign to him. Driven by curiosity he follows the trails of the Unnamed Forces through Germany, Switzerland, Sweden, the United States and Russia- and the forces follow him. The circle closes in Siberia.
