Watch VoirFilms. A portrait of Antje Kosemund from Hamburg and the history of resistance against the Nazi regime. Her father was arrested by the Gestapo in May 1933, her mother died young and her sister Irma fell victim to the Nazis' "euthanasia" murder program. People, places, streets and buildings appear in the conversation with Antje Kosemund, born in 1928. They all tell their story of communist resistance against National Socialism in Hamburg, of a trail in the Aktion T4 extermination program that leads all the way to Vienna. Kosemund's memories are testimony to a life of resistance. A document against forgetting.
