Franz plans to rescue Jadzia, Redliński's daughter. In order to gain Bergman's trust, he sets a trap for Redliński, giving a false meeting place. He uses Eva, asking her to go on a cruise with Jadzia, during which he plans her escape. However, Eva changes the route, and Jadzia disappears.

Franz rescues Jadzia from Eva's hands and hides her with Redliński. Wulf follows them, trying to find secret documents. A group of spies goes to Pszczółki, where Jadzia's mother hid a suitcase with plans. The Germans organize an ambush, but Franz and Johann save Redliński and the girl.

Franz saves Eva from an assassination attempt, but discovers that there is a traitor in their organization. Eva and the Redlińskis are to be smuggled to Sweden, but the Russians and Germans try to stop them. Franz's plan misleads the enemy - instead of by train, the escape takes place by car on back roads.
