The story of Brennende Grenze (= Burning Border) starts after the end of WWI. Polish franctireurs invade the German bordering regions which are to be given to Poland as agreed on in the post-war peace treaties. Luise von Willkühnen's manor is invaded by Ladislaus von Zeremski, his lover Nadja and their gang. They treaten the inhabitants until Luise's son kills Zeremski.
