On Friday October 13, 1307 the Order of the Temple was destroyed. Thousands of its members were captured, tortured and killed. Most of them burned alive by the Church. Including their families. Today, Leonor, a young teacher, flees to a small town in the mountains to try to recover from the death of her husband and the loss of the baby she was expecting. She takes refuge in the daily activity with the children of the school and the friendship that she establishes with Miguel, a forest agent. But the hostility of the inhabitants of the region and visions that torment her lead her to believe that she is going crazy, as if an irresistible mysterious force led her to be related to that story of betrayal and death seven hundred years ago. "La Loba", a strange woman despised by all, will end up revealing the truth of that fascinating and wonderful story.
