Fresh from a breakup with the world’s hottest popstar, music manager Meg Rai (Freida Pinto) leaves New York for London to manage a boyband, 5 Together, who are desperate for a Christmas hit after their latest self-written album flopped. Meanwhile, Blake Cutter (Iwan Rheon), persuaded by his Christmas obsessive, niece, Nina Cutter (Helena Zengel), puts his thrash metal band, Scurve, to one side to write Nina the ultimate Christmas song. When Meg discovers the hit in the making, will this be the Christmas number one the boy band desperately needs or will Blake, the song, and Nina show Meg what truly matters?
