Dave (Adam Levine) has just landed a music deal with a major record label in New York City. Gretta (Keira Knightley) travels with him to America, both as his girlfriend and his musical partner. Dave comes alive on the stage, whilst Gretta prefers to hide away writing songs. But when Dave becomes intoxicated with his newfound fame, he soon forgets Gretta. Alone in a foreign city she relies on the friendship of her entertaining pal Steve (James Corden) to distract her from her broken heart.
Meanwhile, Dan (Mark Ruffalo) is fired from his role at the record label that he co-founded. He has also been exiled from the house that he used to share with his wife Miriam (Catherine Keener) and teenage daughter Violet (Hailee Steinfeld). When he hears Gretta singing in a local bar, he is captivated by her simple, unpolished charm. He suggests that they collaborate, and the resulting album is a tribute to hope, friendship, and New York City.
