The film "Who left the Light ..." is dedicated to the memory of theater director, theater and film actor Vladimir Ageev. He has been called "the main alchemist of modern filmmaking." A student of Anatoly Vasiliev, Vladimir Ageev paved his own path in art. His search and research led him to create his own creative style, to the "Theater of Mystery and Joy". The film uses archival recordings of the director's rehearsals, fragments from performances.
