'Nemtsov' chronicles a remarkable political life. It is a story told by those who knew Boris Nemtsov at different times: when he was a young scientist and took his first steps in politics; when he held high government offices and was considered Boris Yeltsin's heir apparent; when he led Russia's democratic opposition to Vladimir Putin. The film contains rare archival footage, including from the Nemtsov family. 'Nemtsov' is a portrait. It is not about death. It is about the life of a man who could have been president of Russia.
