VIII Century. Christianity spreads throughout Europe while pagan beliefs disappear. Faced with the advance of Charlemagne’s army across the Pyrenees, the leader of the valley asks an ancestral goddess for help. Through a blood pact, he defeats the enemy by giving his life in exchange, but first, he makes his son Eneko promise to protect and lead his people in the new era.
Years later, Eneko faces that promise with a mission: to recover his father’s body buried in a pagan manner next to Charlemagne’s treasure. Despite his Christian faith, he will need the help of Irati, an enigmatic pagan of the area. The two young people will enter a strange and inhospitable forest where “everything that has a name exists”.
