When Lisa Colbert is arrested whilst meeting a contact near Paris, the whole future of Lifeline is put at risk. This also leads to her uncle being arrested and interrogated by Kessler. Whilst in prison, Lisa must decide whether she can trust her fellow inmates who claim to know who she is and how they can help her escape. These events will lead to tragedy, both personal and for Lifeline.
Lifeline, a Brussels-based resistance organisation smuggling downed RAF fliers back to Britain, is endangered when Luftwaffe Major Erwin Brandt blows one of their safehouses. Meanwhile Brandt finds assistance from Gestapo Sturnbannfuhrer Ludwig Kessler, transferred from Berlin to crack down on the evasion lines.
Albert and Lisa continue to be suspicious of Curtis, whilst Lifeline is stretched to its limit trying to deal with several evaders. Meanwhile the Germans capture one evader, Sergeant Walker, who has travelled down the line and is familiar with several of Lifeline’s personnel.
