The Baskerville family curse tells of how a terrifying, supernatural hound roams the moors around Baskerville Hall and preys on members of the family in revenge for a ghastly crime committed by one of their ancestors. When Sir Charles Baskerville is found dead in the grounds, with a large animal footprint near his lifeless body, the locals are convinced that the hound is back. It is up to Sherlock Holmes and Dr Watson to uncover the truth and keep the new heir to the hall safe from danger.
