They fly along steep rock cliffs, dive without oxygen into the depths of the sea, and, on incredibly gruelling bicycle tours, they prove that the human body is able to achieve unbelievable feats. This film presents a wing-suit flyer, an apnoea diver, and an extreme cyclist during their ambitious activities in the top ranks of the sports world, and examines their way of life. What biography, which motives and thoughts have driven those men to become so-called modern heroes? We make contact with their companions and their critics. We learn about the desires and fears of their families and we dare to approach their psyche by also getting to know their best friends. This film offers an unusual perspective of the conditions and the more and more extreme challenges of modern society.
