When the Germans march into Ljubljana (after the Italian capitulation), the Doctor continues with both his official and his secret work, but is caught by the Germans shortly before the end of the war. Will the Doctor remain loyal to his mission until the end, despite the death threats and brutal torture he is subjected to?
