Many years ago Hugo Baskerville had committed an atrocious and deplorable sin for which he was aptly punished but the punishment did not stop there, a terrible curse was put on the Baskervilles which has plagued them for generations. A Hell hound, a beast that is so frightful that the mere act of looking at it causes unimaginable horror to its victims. Legend says that the beast is a bloodhound which can track its victim from one end of the moor to another, it is as big as a lion and as vicious as a pack of wolves, it has great big flaming eyes which can conjure the fires from hell itself.
A descendant of the Baskervilles, the amiable and benevolent Sir Charles Baskerville, takes up his abode at the Baskerville hall. He acts as a benefactor to the village people and makes a lot of friends in the community but always in the back of his mind are the moors and that hell hound. One fateful night Sir Charles ventures in the desolate moor and is found the next day, dead. His face contorted in a ghastly expression and his footprints on the moor suggest that he had been running from something, Nearby, Mortimer(a friend of Charles) discovers footprints of a gigantic hound!
After Sir Charles death, the whole estate is bequeathed to Sir Henry Baskerville, the last living descendant of the Baskervilles. The lone Baskerville decides to take up his residence in the same Baskerville hall and in the same moor. Mortimer has no choice but to approach Holmes for advice and protection. Holmes and Watson vow to protect their client from this curse and end this superstition, but as Watson and Holmes will soon find out legends can sometimes come true.
