Welcome to Batch Magna, a place where anything might happen. And often does...
Sir Humphrey has offered to play Father Christmas at the local hospital, but disaster strikes when he realises he won't be able to buy the sack of toys he'd promised the children.
Rupert, a gentleman of the road, is found asleep in an old car in the Hall's coach house. He is scrubbed up and given a room at the Hall, where two guests are already staying: a businessman and his rather young female companion. When money goes missing from their bedroom, Rupert is accused, and Miss Wyndham, the village's amateur sleuth, decides to investigate the matter.
Meanwhile, local author Phineas Cook has come up with the idea of a resident ghost at the Hall to attract paying guests. All goes smoothly until the ghostly actors spend too long in the pub one evening and their performance descends into sword-wielding chaos.
