The Team face one of their strangest challenges ever: digging through a church graveyard in search of what could be one of the largest Roman structures ever built in Britain.  The Time Team head to the town of Castor to dig in the grounds of a Church looking for remains of a substantial Roman complex. Complicating the excavation is the work of Edmund Artist who took detailed measurements and dug the area 150 years ago. They need to first find the ruins, and try and understand and confirm what Artist saw.

Tony and the Team discover evidence of a dynasty that arrived with William the Conqueror and went on to produce two queens of England: Elizabeth I and Lady Jane Grey.  The Time Team visits the ruins of the home of the Grey family, and property the family had lived on for nearly 800 years. The team tries to establish the history of a castle built on the site in the 12 century.
