Germany's rivers are running low. Hotter summers, falling groundwater, and dried-out soil have turned water management into a political fight across three states, and this film follows the scientists, farmers, environmentalists, and politicians caught in it. Decades of straightening the Unstrut, Mulde, and Elbe rivers for agriculture and shipping stripped away the floodplains that once absorbed floods and recharged drinking water supplies, and the film traces what that engineering cost downstream. Renaturation projects aimed at reconnecting rivers to their floodplains promise better flood protection and climate resilience, but they also mean farmers losing land and communities losing certainty about how water will behave near their homes. Interviews on riverbanks and in fields lay out the conflict plainly: conservationists pushing to let rivers spread out again, farmers wary of losing productive ground, and officials trying to referee between them. The film doesn't resolve the argument so much as map it, leaving the question of how much water Germany can retain in its landscape genuinely open.
