After having disappeared for almost 80 years and despite the obstacles, the wolves are in the process of finding their former territories. This film tells the great mystery of the dispersion of wolves: how the young wolves leave the territory where they were born, and the way in which these adventurers set out to conquer new territories. For two years, Jean-Michel Bertrand conducted a real investigation to try to understand the complex and erratic functioning of these young wolves, their encounters with their fellow humans and the opportunities to get together. In the wake of nomadic wolves, the film tells us how they must cross hostile territories already occupied by their fellows and in which they are not welcome, or others, more numerous, colonized by humans. Fortunately, there are wilderness areas known only to these adventurers ... After La Vallée des Loups released in 2017 and which recorded more than 200,000 admissions, Marche avec Les Loups continues Jean-Michel Bertrand's adventure with nature.
