Natalia, a nun from a remote Russian monastery, comes to Moscow 17 years after the terrorist attack in Dubrovka Theatre. She was sent there to organize a memorial evening for the victims of the attack that happened in October 2002. We soon learn that Natalia and her family were the witnesses of the attack. Almost forgotten now by the outside world the organizers and participants of the memorial evening or the Conference (as they were asked to call it officially) are made feel like a burden by the rest of the society. Following the chronology of the events as told by a few participants in the memorial evening we learn the dark details of Natalia’s personal story.
