Monika is a 13-year old singer. She has just arrived in Dublin from Lithuania and lives in a small apartment on a bustling housing estate with her mother, Jolanta, and grandmother who has dementia. Even though Jolanta is a talented pianist, she works hard at a local fish factory. Money is scarce, and she ends up selling her daughter’s prized keyboard. Unlike her mother, Monika refuses to give up on her musical dreams and is convinced that the mother-daughter duo will get their big break. After performing at a funeral, Monika's dreams finally seem to be answered when they are invited to play at a place enticingly called The Castle, but Jolanta refuses instead accepting a promotion at the factory. With single-minded determination Monika embarks on an endless series of schemes to buy back her keyboard, and ultimately get to The Castle.
