This is set during the final weeks of German occupation. Paul Vercors, the leader and sole survivor of the Communist cell to which Max belonged, begins a conspiracy of revenge against Albert. He lodges an accusation with the authorities that Albert murdered his wife. With Albert in prison for much of the series, responsibility for Lifeline falls to Monique. She becomes increasingly independent and eventually her relationship with Albert collapses, owing to his aloofness and her realising that he is more concerned about money than her. After the Germans severely restrict travel to and from Brussels and the Communists sabotage the main railway line, the evasion lines are closed. The rescued airmen can now only be hidden while they all await the end of the war. With Albert away, Monique and Natalie face accusations of being German collaborators, prostitutes and black-marketeers. As news of the Allied troops' imminent arrival reaches the streets, the Germans find it increasingly difficult to keep order and eventually they leave the Belgians to their own devices.
