DI Vivien Friend investigates the murder of a young woman whose remains have been found preserved in a concrete tomb at a demolition site. The only clues to her identity are a healed scar along her left hand and a puncture mark at the base of her spine from a medical procedure.

The police investigation leads to a 3 year old missing persons case in which a young girl vanished from her parents' pub without trace.
