Renovations at an abandoned farm have uncovered two bodies: a man known to be an IRA member missing since the nineties, and a young girl whose identity remains a mystery.
As Paula attempts to discover who the girl is and why no one is looking for her, an anonymous tip-off claims that her own long-lost mother is also buried on the farm.
When another girl is kidnapped, Paula must find the person responsible before more lives are destroyed. But there are explosive secrets still to surface. And even Paula can't predict that the investigation will strike at the heart of all she holds dear.
