Heartbroken when he rejects her for the fame and fortune of a big solo contract, Gretta finds herself alone and far from home. Just when she’s decided to move back to London, life begins to look up when a down-on-his-luck record producer Dan (Ruffalo) stumbles upon her singing during an open mic night.
