When London-based barrister Rachel Mortimer visits Wales to defend a man charged with sexual assault, her cross-examination of the key witness, DC Gwil Humphries, affects both their careers.

When a corpse is found in the freezer room of a butcher's shop, Rachel and Humphries suspect a sinister reason behind the man's death.

A young boy's body is found in a ravine and the locals believe that his death is a human sacrifice. A suspect is arrested, but Rachel thinks there may be another explanation for the tragedy.

An inquiry is launched when a woman dies in the county hospital after her baby is born.

Rachel and Humphries hear a case that has split a community. Wendy Frampton has been missing for several years, and her mother believes she has been murdered by her husband. But is the truth more sinister than she ever thought?
