Curtis’ cover has been blown and Kessler knows that he is part of the resistance. To avoid endangering the others, Curtis goes to ground in Brussels. Knowing that Lifeline is at last in his sights, Kessler orders that all routes out of the city are blocked and co-ordinates a house-to-house search throughout the city. In desperation, Curtis goes to the Candide to ask for help, and Monique comes up with a highly audacious escape plan.
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.
