Alice Guy-Blaché began making films in 1894. She had an illustrious career in both France and the U.S, directing over 1000 works. In 1919, however, she abruptly disappeared from the history of film. Narrated by Jodie Foster, the documentary is both a tribute and a detective story, tracing the circumstances under which this extraordinary artist left us, and charting a path towards her reclamation.
