In this episode, the crew is in the West of Britain and is joined by archaeologists in the lab to check out some new finds and figure out what they mean. These finds include the lost World War I training trenches on Salisbury Plain, Britain's first double henge-discovered just down the road from Stonehenge-where the evidence suggests our ancestors feasted and made sacred offerings as part of a visit to the ritualistic Stonehenge landscape. They also investigate luxury foreign goods discovered at Tintagel, the legendary childhood home of King Arthur.
