Tony and the team tackle a huge Roman fort in County Durham. The stronghold was part of the defence of Dere Street, the main Roman road from York to Hadrian's Wall. The fort has fine mosaics and preserved rooms, but the Team have just three days to find out everything they can about the 'vicus', that's the civilian settlement around the fort, vital for the smooth running of the military machine and providing for the pleasures of the men garrisoned there. However, they soon discover something even more exciting during the dig - a series of military mausoleums, the first discovery of its kind for over 150 years. They also discover the remains of food eaten by the descendants of the dead during ritual meals.
