The team carry out the first-ever excavation of a cemetery at a Roman fort. This one is a World Heritage Site on Hadrian's Wall, delineating Roman Britain's northern boundary. Dead soldiers would have been cremated, and Jackie makes an experimental funeral pyre with cuts of meat. Unfortunately a downpour extinguishes the flames; but a second attempt succeeds. Stewart is more interested in the erosion of the land, which may have been caused by flooding or an earthquake. After some frustrating dead ends, they eventually piece together a plausible description of the site, recovering some interesting finds before time runs out on the third day. They are joined by site director Tony Wilmott and Roman finds expert Lindsay Allason-Jones.
