There have been several sightings of a ghost in the Cathedral and attention turns to the Bishop, who is called upon to perform an exorcism. The Bishop, however, decides to hunt out the ghost by performing an all-night vigil in the cloisters.

Having endured one of the Dean's parties the previous night, the Bishop and Archdeacon are not over-pleased when Noote forces them to attend another. But they're in for a surprise when the Dean's delightful sister, Hilary, charms them both and suddenly there's a contest to win her affections.

The Dean agrees with St Paul that 'a Bishop should be given to hospitality' but he's taken by surprise at the outcome.
