At Gestapo headquarters, Kessler takes an instant dislike to the newly arrived Luftwaffe Major Hans Dietrich Reinhardt, who has joined him in a final concerted attempt to crush the evasion lines. As the Allies continue to advance from the invasion beaches, Lifeline must continue their efforts in getting airmen back to Britain, but when Natalie attempts to guide two evaders down to Spain, it becomes clear that their work may at last be over.

An assassination attempt has been made on Hitler, and Kessler believes that Reinhardt is involved in the conspiracy. He begins to gather information that he hopes will provide his colleague’s guilt. Meanwhile, Albert becomes aware that the Communists are once more out to get Lifeline, and that he is their target.

Albert is finally released from prison and reunited with Monique. The Lifeline personnel continue to be in danger of reprisals from their own people and the Communists for alleged collaboration with the Germans, but Albert refuses to leave the Candide. The Allies are still making their way towards Brussels, and Natalie and Alain join the offensive. As Kessler and his men leave the city, Reinhardt stays behind to complete his investigation into Lifeline and pays one last visit to the Candide, just as Paul Vercors emerges to take ultimate revenge on Albert.

Vercors has taken Albert, Monique and Reinhardt prisoner, and plans to hang Albert as a collaborator and a murderer. Only the Allies, helped by Natalie, can save him but they have only just entered Brussels. Meanwhile, Kessler and Madeleine are trekking on foot towards Germany through the Belgian countryside. To evade capture by the Allies, Kessler decides to take on a new identity.
