It's been a year since Rima Khalaf died in a fall from the Black Rock, deemed to be a tragic accident by the police.
But her grieving parents are dissatisfied with the police investigation, so DS Amanda Pitt is sent north from Glasgow to the small town of Clachdubh to re-examine the case.
Despite the suspicions of the distraught parents, all the circumstances seem to confirm Rima's death was indeed a tragic accident, until another woman is also found dead in the town.
Frustrated by the lack of any real evidence, DS Pitt pushes the limits of legality in her quest for the truth.
