The series retells the story of Irish mythology and tells the story of Eachtach, a young hunter whose parents are on the run from the ghosts of their past and who needs to learn to challenge the heroes of her childhood.

Eachtach's parents were once a great hunter and a princess. When Eachtach was born, they were on the run from a powerful man who was once betrothed to Eachtach's mother. Eachtach spent her life in the wilderness, running from that man. One day, while out hunting for her family, she spotted a strange raven and followed it on an adventure that would allow her to seek revenge.

Many years before the time of Eachtach, a young hero named Fionn Mark Combehare grew up to become the leader of the Fianna, a band of hunters who protected the land from invasions and magical threats. He grew into one of the greatest heroes of the land, however the death of his first wife changed the course of his life and led him to the acquaintance of a young and beautiful princess.
