Lotte Eisner was a journalist, chief curator at the Cinémathèque Française at the time of Henri Langlois, author of the book The Haunted Screen (1952) — analyzing German expressionist cinema — and admired by directors from Fritz Lang to Godard. However, she is still a little-known figure, something that this film wants to change. This mission is accompanied by archival images, film excerpts and interviews with figures such as Wim Wenders and Werner Herzog.
