In the north of the Iberian Peninsula, an imposing mountain range of more than 400 km rises as a great barrier parallel to the coast of the sea that bears its name, the Cantabrian Sea. On its other side, the Cantabrian mountain range is full of canyons and dense continental forests of beech, oak and chestnut trees.
It is the perfect place to hide for a large number of animals and other forms of life that have lived here since time immemorial. But above all, it is the territory of one of the most formidable creatures in the northern hemisphere: the Cantabrian brown bear. And it is precisely this fabulous animal, one of the ones we have chosen to lead our film.
