The series was set in the British town of Chelmsford in the year AD 123, and concerned the power struggle between Roman governor Aulus Paulinus (Jimmy Mulville) and the British chieftain, Badvoc (Rory McGrath). Britain is a miserable place, cold and wet – just the place to exile Aulus for accidentally insulting the Emperor's horse, but also give him something useful to do. Aulus was a rather delicate Roman, who was usually outwitted by the scheming Badvoc, who hadn't had a haircut for twenty-five years. Many of the other regular "Hat Trick" actors, previously seen in shows such as Who Dares Wins, also appeared.
