Mein Kampf has never gone out of print, changing hands in bookshops and online decades after its author's death, and this film asks how a 700-page book written in a Bavarian prison cell in 1924 became both a founding text of genocide and an object banned, bootlegged, and studied ever since. Historians and archivists trace its writing, from Hitler's dictation to Rudolf Hess through its editing, its numerous postwar re-editions, and the copyright battles that followed Bavaria's ownership of the text until 2015. The film examines whether the war and the Holocaust were already legible in its pages in 1925, or whether readers only saw that clearly in hindsight. It also asks a blunter authorship question: how much of the book is Hitler's own thinking versus material absorbed from the antisemitic and nationalist writers around him. Archival photographs, period editions in translation, and expert interviews carry the argument, treating the book as evidence rather than relic.
