The Amazon is one of the wildest and least explored parts of the planet. Encompassing 6 countries and 2 million square miles of forest, river and floodplain, it has the highest diversity of life on the planet, but what lies below it is truly shocking. In its deep muddy rivers, clear streams and expansive floodplains a freak-show of fish life has exploded, with some of the strangest shapes and weirdest adaptations on Earth.

The white chalk cliffs of Rügen are among the most impressive natural monuments on earth, which the painter Casper David Friedrich immortalized for posterity as early as the 19th century. Germany's largest island with its seaside resorts from the Gründerzeit, its smaller side islands and peninsulas that give it its shape, its lagoon-like Bodden waters, the dense beech forests, the yellow rapeseed fields and the meadows, the shady tree avenues and the white sandy beaches is not only a magnet for tourists, but also a unique natural paradise in the middle of the Baltic Sea, a habitat for the rare white-tailed eagle, fallow deer, raccoon dogs and badgers as well as a resting place for huge swarms of migratory birds such as geese and cranes that can be heard trumpeting from afar.

An Otter Study is a 1912 British short black-and-white silent documentary film, produced by Kineto, featuring an otter in its natural habitat, including groundbreaking footage of underwater hunting scenes. The film provided a novel treatment of the creature, which had previously appeared on film only as the victim of hunt films, with the unique underwater footage, shot by a cameraman behind glass in a tank concealed on the bed of the river in the opening scene, and a concluding scene, excised from the surviving print, in which it escapes the hunters. It was long thought lost until footage from a 1920s Visual Education re-release of the film, re-edited under the supervision of Professor J Arthur Thomson of Aberdeen University's Natural History Department, was rediscovered.

But the two men share a common dream: to see a wolf pack live, grow, and spread out. One day, their search leads them to a hideout in no-man's-land between Iceland and Russia, a place conducive to a different temporality. The wait begins. Over the seasons, they will stand there in these eight square meters of wood, silent amid an unchanging scenery, until they gradually become part of the “picture” and immerse themselves in the life of the wolves.
