Secret Army - Season 1 Episode 3

The Jewish population of Brussels is being systemically deported according to colour-coded identification papers developed by the Germans. Curtis becomes involved with a Jewish family hiding out in the city and asks Lisa if Lifeline can help, but Lisa is unwilling to put the line, which is supposed to help RAF evaders not Jews, at risk. Curtis himself is still under suspicion by Albert, when Lisa’s uncle, bank manager Gaston Colbert, identifies Belgian banknotes he brought over from London as forgeries. Kessler obtains some of the notes, and realises that they are too accurate to be real and have been made by the Belgian treasury plates, which were evacuated to London before the German invasion. He believes that the notes will bring him closer to Lifeline.
