The team are in Hooke Court, Dorset to investigate a moated manor house with a mysterious past. Now used as a school, the grounds contain remains of buildings from the past 500 years and as the trenchers begin their work, the finds start to pile up. Though they are particularly looking for evidence of the Civil War, there are signs of activity from several different periods, including medieval and Tudor. The team are joined by historians Sam Newton and Jonathan Foyle. The school's pupils get involved in all aspects of the dig. As usual, Stewart has his own ideas about the site, and is skeptical about the idea of a moat.
