Every zoo aims to protect animal species from extinction. During the Second World War, the Warsaw Zoo carried out its function in a rebellious manner. Once the war began, some animals were killed by the Nazis and the others were transferred to the Third Reich. The abandoned enclosures were taken over by the species most endangered by warfare: the man. The Jews escaping the inevitable death and the Home Army soldiers found shelter in the empty stables, kennels, and aviaries as well as in the house of Jan Żabiński, the then Director. The Zoo offered shelter – sometimes for a day, rarely for a few months – to several hundred people. The exact number remains unknown. We will try to tell this incredible story by means of metaphorical shots of animals, abundant archival footage, and interviews with the last living witnesses.
