Watch MoviestoWatch. Monolithic power plants; billowing columns of smoke; the backdrop of a red sun. Sirens is an experimental short documentary that captures Germany’s coal-fired power plants in their final years of generating energy. Shot entirely from helicopters, the film takes us on a journey through industrial wastelands, thus recalling the passage of Ulysses’ boat through the Sirens’ strait. An odyssey through the dystopian industrial world that has left a permanent mark on earth’s ecosphere.
