At the height of the summer of 1941, the Germans are advancing rapidly. Intelligence plays a special role in this war. The elite of Soviet intelligence is a secret department of the General Staff of the Workers’ and Peasants’ Red Army. There is Pavlovsky’s group, which carries out the most difficult assignments. Pavlovsky himself is the son of a repressed general, but this status does not prevent him from becoming one of the very best intelligence officers. The hero can carry out the most crucial operations, upon which the fate of an entire front and the state depends. This time, he must save an academician who works on encryption technology. The Germans badly need such a specialist. The scientist was vacationing with his family in Belarus when the war began. Due to the rapid advance, the man found himself in occupied territory. Pavlovsky must rescue or eliminate this luminary of Soviet science. His group will also need to destroy a captured defense plant, kill an important Nazi official, and return a double agent to the Germans.
