Sandi takes her first ever trip to Hadrian's Wall in Northumberland to discover what life would have been like for the soldiers, their families, the traders and enslaved people at the edge of the Roman Empire almost 2000 years ago. At the nearby site of Vindolanda, Sandi helps clean a massive size 14 boot, discovered in one of Magna Fort's defensive ditches.

Sandi is in Essex, helping to find and identify the wreckage of a Second World War US Army Air Forces fighter plane in the hope of repatriating its pilot. As archaeologists carry out a forensic search, Sandi unearths training logs and a weather report from the day the plane crashed, gaining further insight into a young life cut short.
