There's much excitement in Aidensfield as Lord Ashfordly returns with a new wife in tow and throws a spectacular Christmas party to celebrate his marriage, and the villagers are pleasantly surprised when they discover how glamorous and charming she is. However, all is not well for the newly-weds as a series of violent hijackings leaves them shaken. Merton assigns Mike to act as a personal bodyguard for his Lordship's new lady, but the intrepid officer's suspicions are soon aroused by the blushing bride's decidedly odd behaviour. Meanwhile, Vernon's Christmas tree delivery service suffers a blow when David crashes the van, and the pair inadvertently jeopardise the future of Bernie's garage when Joyce Jowett requires their funeral service for her sister.
