An international team of experts assemble to investigate the discovery of a 4,000-year-old body found preserved in an Irish peat bog in Cashel, Co Tipperary. Led by Ned Kelly of the National Museum of Ireland, the archaeologists look at whether the find will help prove Ned's theory that these mummified corpses were once ancient kings, and what clues the cadavers found in the boglands of northern Europe can offer to explain the history of ritual murder.
