Central Ireland's waterlogged ground perfectly preserves stunning evidence of brutal ritualistic killings from the prehistoric Iron Age.

Central Ireland's waterlogged landscape is no ordinary ground. Here, the moist earth halts decomposition, perfectly preserving stunning evidence of brutal ritualistic killings from the prehistoric Iron Age, over 2,000 years ago. These are not skeletons or mummies, but the soft tissue and remains of people trapped in time. The perpetrators of this ancient violence are well beyond the reach of law, but there are still fascinating secrets their victims will share, if only modern science knows how to ask. NOVA is granted exclusive access to the investigation of two recently unearthed and exceedingly rare bog bodies. Viewers enter the lab with the experts as they push archaeological forensics to its limits, aiming to unravel how these people lived and how and why they died.
