The wise druid Cathbad (Rolf Drechsel) predicts in a mild night in autumn, that the daughter of Fedlim and his wife Derdriu (Verena Schröder) will be the most beautiful and bravest woman Erin has ever seen, but she will also bring sorrow and doom over the men of Emuin Macha because of her beauty.
At King Conchobar's (Holger Krebs) behest Derdriu raises under the charge of the magician Leborcham (Lara Martignago) to marry the king, when the time comes. But Derdriu has other plans: When she heard about the druid's prophecy, she gets Noisi (Thorsten Gabriel Reiter), a handsome peasant's son, with whom she falls in love, to abduct her and to flee.
Together with Noisi's brothers Ardan (Christoph Karg) and Annli (Johannes Kunzmann) they go on a journey, on which they get in extreme danger again and again and meet the king's soldiers but also get in trouble with the king of Alba and some other curious guises, from which they never know if they can trust them or not.

Based on the irish-celtic tale "The Exile of the Sons of Usnech" from the „Ulster-Cycle“ there comes an historical lovestory set in the celtic mythology. Be curious on an romantic, exciting, dramatic history epic, filmed on original locations in Ireland and Northern Ireland as well as in Germany and France.
