Sam is a former high-profile advertising executive whose life has been torn apart by the tragic death of his son. Off the grid, living on a docked sailboat, he drowns his pain in alcohol. When Sam discovers a box filled with his son's demo tapes and lyrics, his own child's musical talent is a revelation for him, a grieving father who felt he'd been absent from his son's life. Communing with his deceased son's dashed dreams, Sam learns each song and eventually musters the will to play one at a local bar. When Quentin, a young musician in the audience, is captivated by the song, the unlikely duo forms a rock band that becomes surprisingly popular and changes both of their lives.
