Skiing, snowboarding, slab surfing, mountain biking and speed riding are the focus of this year's La Nuit De La Glisse Cinéma film. In this film, Thierry Donard introduces us to "Xtreme" human beings who, through their lives and their resilience, accomplish extraordinary feats. Across the world and through breathtaking landscapes, see how our athletes deal with fear and the changes that face them.
