Sam Anthamatten and Victor De Le Rue push new boundaries in the wildest corner of Alaska. A bush pilot drops the small crew of five on a remote, unexplored glacier to conquer the spine walls in a series of ascents, each one more committed. Narrator Jérôme Tanon describes with honesty and a touch of sarcasm what exactly is going on here. Above all, he wants to feel what it’s like to be in their shoes, to understand what so-called “free riders” are made of, and what could be the purpose and beauty of “freeriding”.
