Nans and Mouts start from scratch, naked and penniless, in the Lyon region with the goal of going to the Morvan Forest to meet the big bad wolf. Armed with audacity and spontaneity, they must rely on the generosity of the people to provide them with clothing, food, and accommodation. They meet Jérémy, who recently recovered from serious health problems, and Cédric, who is depressed after a buildup of personal problems. The two vagabonds will discover people full of humanity with very touching personal stories.
