Secret Army - Season 1 Episode 5 Second Chance

The safety of Lifeline is at risk when Albert deduces that the Candide is being watched by a Gestapo spy, while Lisa continues to resent Curtis’ presence and his domineering take-charge manner. A wounded RAF evader, Finch, finds sanctuary with Hans Van Broecken, a Dutchman who lives on a barge with his wife Lena. Finch plans to desert the army and escape to Switzerland and finds a kindred spirit in Hans, who is in fact German and deserted during the First World War. Hans plans to take Finch to Switzerland himself on the barge, but Lifeline becomes involved when Lena receives a visit from her niece – Natalie. However, helping evaders escape to comfortable Swiss internment is not Lifeline’s purpose, and how can Finch be involved with Lifeline with the Candide under German surveillance?
