This time, Emma Baus sets off to meet the animals of our forests. Foxes, wild boars, but also deer, tits and squirrels, all in perpetual search of strategies to survive the invasion of man on their territory. This sumptuous journey takes us from the Northern Vosges to the Ile de France via Haute-Marne, to try to better understand and above all respect the needs of the animals of our forests. Guided in the field by passionate biologists (ONCFS, MNHN, INRA), her team manages to film wild fauna in freedom. Magical moment of the bellowing resonating in the misty forest. Touching encounter with small squirrels close to humans or wild boars fond of corn. Discovery of the great tit, predator of processionary caterpillars and the fox, efficient hunter of voles.
