Adolf Hitler's death in a Berlin bunker in 1945 is the accepted historical record, but declassified FBI files show the Bureau spent eleven years chasing a rumor that he survived it. The film follows that paper trail: informant reports of a U-boat crossing that supposedly carried Hitler and several confidants to Argentina, and testimony from people who claimed later contact with him there. It places the story inside the real network of Nazi "ratlines" that got officials like Adolf Eichmann out of Europe, and it examines the suspicions swirling around Juan Domingo Perón, whose government took in former SS men and drew accusations of sheltering fugitives at the highest level. Agents' interview notes and internal memos are read out to show how seriously the claims were investigated, and how thin the corroboration stayed. The FBI ultimately closed the case without proof either way. The film keeps that ambiguity intact rather than resolving it, leaving Hitler's fate in Argentina as an open file rather than a solved one.
