Aspiring director Kishorváth seeks approval for his debut film, based on his grandfather’s odd ’60s protest: he and friends formed a “Danube Indians” tribe, donned moccasins and withdrew from society under strict moral codes. In the paranoia after ’56, the group’s strange weapons, secretive speech and ties to Americans draw government suspicion. When a censor on the approval board, whose own family was involved, challenges the tale, Kishorváth digs deeper into his grandfather’s true story.
