Meg, a music manager, travels from New York to London to manage a boy band, Five Together, and find them a Christmas number one to bolster their flagging career. She finds a song on the internet posted by an ailing thirteen-year-old girl, Nina, and tries to obtain permission to have the song re-recorded by Five Together, but she discovers she has competition from the songwriter, Nina’s uncle Blake. What follows is a romantic comedy about two worlds colliding – with a young woman at the centre who desperately wants her uncle to find love and for his song to hit the number one spot by Christmas Day.
