Tracing the history of an old family photograph, the filmmaker travels to Poland with a group of her parents' contemporaries. Fifty years after surviving the Holocaust, the elders return to their hometown, Poddebice, to conduct a memorial service in the Jewish graveyard. They find an empty field, marked by a lone tablet, the only testament to the history of this place to survive the wartime desecration. Through a montage of archival footage and interviews “House of the World” examines the Holocaust through the eyes of survivors and their descendants and explores the relationship between objective history and personal memory.
