June 1941. Only a few days remain before the beginning of the Great Patriotic War. Obersturmbannführer Stierlitz is sent to Krakow for a meeting with the “Führer” of the OUN—Stepan Bandera—who will play an important role in preparing units of Ukrainian nationalists to carry out punitive operations on the territory of the USSR. The plans of Bandera’s people include creating an independent Ukrainian state, but this is completely opposed to Hitler’s great racial idea: the territory from the Prut to the mines of Donbas must become land belonging to German colonists. The Center instructs Stierlitz to continue gathering information about the nationalists and to report exact data about the planned attack on the USSR: the main directions of the strikes and the forces that will take part in them.
