Keeley and Jude are closer than blood. Inseparable since childhood, they share everything- clothes, secrets, booze and blame. So when they wake up after a new year's party to find Keeley's boyfriend stabbed to death beside them, they agree to share something else- the story they'll tell the police.
But who is that story really meant to protect? Is Jude risking her bright future to protect her friend? Is there more to sharp-eyed Keeley than she lets on? Or are they conspiring to let Keeley's brother get away with the drugs he's been selling in their small town?
As the murder investigation sends ripples through their community, the history of the girls' claustrophobic relationship comes under scrutiny and they start to realise they might not, always, have shared as much as they thought.
