S1, E1: Ian and Butzy are searching for treasure in Cork, Ireland's largest county. They go picking at an 11th Century castle built by the grandson of Brian Boru, high king of Ireland. Undeterred by its turbulent past and tales of ghosts, Ian discovers a mysterious stone head, a carving of a famous figure from Irish mythology, and a gadget he just loves, even though it dates not from the 1060s but the 1960s.
