I watched the movie Black Book. This is the story of a Jewess in Holland in WWII.
She tries to flee the country but her escape does not work and she joins the resistance and is a spy for a bit.
Most of her friends and helpers are killed. She also falls in love with a Gestapo guy, but he is also killed at the end of the war and at the time of the German surrender. Part of the resistance and one or more of the Jews were in fact working with the Nazis.
I think this is a very good movie.
