Thirteen-year-old Monika lives with her mother, Jolanta, and her senile grandmother in Dublin. The music-loving girl performs for the Lithuanian community accompanied by Jolanta, a trained pianist who works in a fish factory. By chance, a music producer hears them and invites Monika to sing at Galway Castle, a famous concert venue. But Jolanta can’t pay the 120 euros in travel costs. In fact, she has so little money, she has to pawn her piano. In a desperate move to make her dream come true, Monika kidnaps her grandmother and demands ransom from her mother … “The Castle” is more than just a gripping coming-of-age film. It also provides a window into the Lithuanian diaspora in Western Europe, where there is a thriving black market and everybody is out for themselves.
