The subtitle of Jean-Marie Straub and Danièle Huillet’s first feature, from 1965,  “Only Violence Helps Where Violence Reigns, ” suggests the fierce political program evoked by their rigorous aesthetic.

The subtlest of cues accompany the story’s complex flashbacks. The middle-aged Robert Fähmel tells a young hotel bellhop of persecutions under the Third Reich; his elderly father, Heinrich, an architect famed for a local abbey, recalls the militarism of the First World War, when his wife, Johanna,  incurred trouble for insulting the Kaiser. A third-generation Fähmel is considering architecture, just as the exiled brother of Robert’s late wife, returns, only to be met by their former torturer, now a West German official taking part in a celebratory parade of war veterans.
