Pierre (Jean Dujardin) is a celebrated writer with a penchant for extreme experiences. One drunken evening he climbs the facade of a building and falls several storeys. The accident leaves him in a deep coma, and when he emerges he is barely able to stand. Against everyone's advice he decides to hike alone across France - from Provence to Mont-Saint-Michel - along forgotten trails. Based on the award-winning autobiography by Sylvain Tesson - who also appears in the documentary, The Velvet Queen.
