A chance encounter between a disgraced music-business executive and a young singer-songwriter new to Manhattan turns into a promising collaboration between the two talents.
Gretta (Keira Knightley) and her boyfriend Dave (Adam Levine) are together since high school and compose music. When Dave sign a contract with one of the biggest record companies move out together in New York to begin life, which they always dreamed of. Dave, however, quickly gained fame and leaves Gretta early. Everything changes, when Gretta meets during her performance in a remote bar in the East Village of former music producer Dan (Mark Ruffalo). Dan is also not doing very well because of his failure in a marriage and the recent fired from work, which he tries to solve by drinking alcohol. As he is listening to Gretta´s singing he decides to bet everything on her talent, and upload an unconventional album in the streets of New York. The accidental meeting of two disillusioned people will give a birth to the music that maybe won´t conquere the world but definitely capture hearts of all.
