John Carney directs this musical comedy set in Dublin about the attempts of 15-year-old Conor (Ferdia Welsh-Peelo) to woo new girl Raphina (Lucy Boynton). When Conor has to start attending a rough boys' school as his parents Robert and Penny (Aidan Gillen and Maria Doyle Kennedy) are facing financial hardship, he determines that the way to get model Raphina to spend time with him is to persuade her to star in his band's music video. Conor is ecstatic when Raphina accepts. The only problem is, he doesn't have a band... Conor needs to form one, and quick! With the advice of his wise older brother Brendan (Jack Reynor), and his friends, he might be able to pull it off.
