Sherlock Holmes' greatest adventure awaits him and Dr. Watson in Dartmoor. The devil's own hound is said to lurk in the deep shadows of the moor, and its target is the owners of Baskerville Hall. The curse over Baskerville Hall has claimed the life of the most recent owner, and now the new master has been threatened. It is up to Holmes and Watson to untangle the clues that all point to a supernatural origin. Could the hound really be the vengeful spirit of doom set upon the house of Baskerville, or is it the plotting of a most devious mind bent on leaving a trail of blood and bodies?
