Harley is a troubled 13-year-old girl who wants to end her own life and there's only one woman who can find out why.
When Harley is sectioned after attempting suicide, she ends up in Casey's care under a 28-day care order. But before Casey can even get her back to the safety of her home, Harley hurls herself out of the moving car.
Harley has a family - a widowed mother and older sister Milly. But Milly has left home and her mum, who has addiction issues, feels unable to cope.
Despite the dysfunctional family, Casey suspects there is more to Harley's distress and after weeks of gentle coaching, a sudden breakthrough sheds light on the disturbing truth - Milly and her mum are not the only people in Harley's life. There is a man, a very dangerous man indeed.
