In a spooky Portuguese village, there is a legend. The legend of the wolf-child. Wished for and born on a full-moon night. It all began when a young peasant girl, desperate for a son, makes a wish to a creature from the forest.

The wish? A child to call her own. But the creature of the forest curses the woman. When he grows up, the child will bring teeth and blood to the village. Years pass, and the child becomes a man, tormented and persecuted by the villagers. He is torn between his beastly nature and a friendship with a young witch. The boy must find out who, or what, he is. Together, the child-wolf and the witch will try to break the curse and find their place in the world.
