Lord Bath has handed control of Longleat to his son Ceawlin. But running a £190 million aristocratic estate brings unique challenges.

In the attic, Ceawlin finds memorabilia his grandfather collected -including an original watercolour by Adolf Hitler. In the safari park, a vast new animal house is being built for ageing elephant Anne. But her keepers are beginning to worry she is too frail to make the half-mile walk from where she is living now. And at the peak of summer, with the estate full of visitors, disaster strikes on the miniature train, with an incident that makes television news headlines.

Meanwhile, Ceawlin's wife Emma is pregnant with the future heir to Longleat. But she finds herself missing friends and family from her old life in London, and she wants to find a role for herself on the estate.
