Gaynor Jacks has come back home and is hiding in her teenage bedroom. But Mum Brenda makes sure she gets out and faces up to the friends she left behind: manipulative Mel, club-weary Kelly and angry Becky.
Just when she is settling back in, dad Roy decides to spruce up Gaynor's room 'now she's having boys over'. Meanwhile, Becky finds out about an age-old insult from Mel, which blows the group apart. Gaynor must choose: Becky or Mel.
As the girls wake up from a boozy sleepover, Gaynor gets a nasty shock - an invitation to a school reunion. Whether she goes or not, she's finally going to have to face up to all the rumours about why she went and what went wrong.
