An aspiring rock star contends with the prospect of giving up his dreams during an emotional battle for shared custody of his six-year-old daughter. Joby (Paul Dano) always dreamt of the day that the years he spent as a struggling musician would finally pay off. But the older he gets, the less likely it seems that will ever happen. Presented with divorce papers by his estranged wife (Margarita Levieva), Joby understands that the only way he will ever see money from the sale of their home is to sign his name on the dotted line. Upon realizing that by signing the papers he will also forfeit custody of his daughter Ellen (Shaylena Mandigo), however, the aging musician begins to have second thoughts. Meanwhile, as Joby's lawyer (Jon Heder) tries in vain to reverse the decision, the conflicted father takes a break from his starry-eyed girlfriend (Jena Malone) to meet with his daughter, and perhaps take a second shot at fatherhood.
