About the series
Based on the novel of the same name by Dmitry Polyakov-Katin. In the summer of 1943, the Soviet leadership learns of the progress German physicists have made toward building an atomic bomb. The task of obtaining secret information about the creation of a new weapon capable of changing the course of the war falls to Frans Hartman, a Soviet agent operating undercover. A complex, multi-stage operation begins. Hartman draws in the head of German intelligence, Walter Schellenberg, who has his eye on the German scientific genius Werner Heisenberg. The Gestapo also gets involved, assigning "German Foreign Ministry employee" Dori to keep watch over Hartman. Meanwhile, in Moscow, work on the Soviet atomic project intensifies under the leadership of the talented physicist Igor Kurchatov.
