Katie's situation isn't exactly ideal. Dad's moved to California to be with his fiancée, while Mum's been seeing some bloke called Adrian she met down the pub. Even her big sister Amanda's busy playing bass in her new band. It's like Katie doesn't exist. So, videoed by her mates, she sings a song about what's wrong with her life. 

Putting it up online will shame everyone into treating her with a bit more respect. And then, of course, she'll take it down again. Before she can, the song goes viral. And while Amanda's ranting and Mum's giving her the silent treatment, Adrian's old music industry mates are getting in touch in droves. 

Fresh, fun and authentic, it seems that Katie's just what everyone's been looking for. Katie's not sure she's ready to be a superstar, but even she admits that her family could do with the cash. And being the voice of the next generation could be pretty cool. But as the money starts to pour in and her fame grows, things get weird. Why do so many people want Katie to fail? Can she perform in front of strangers? Who can she trust? And has all this been a massive, hideous mistake?
