Adaptation of Yasutaka Tsutsui's sci-fi black comedy set on Planet Porno, where any plant, animal or human can mate with any other species. It is a place where Darwin's rule of evolution - the survival of the fittest - is no guide to staying alive, and Eros rules. The three astronauts who strike out into the jungle are woefully ill-prepared for what is to come. With Ophelia Bitz, Donald McCleary, Stewart Porter, Ron Donachie, Crawford Logan, Morag Stark and Geoff Noar.
