In the outskirts of 19th-century London, the mysterious Baskerville Manor is swallowed by fog. Sir Charles Baskerville is found dead near the moor, eyes wide open, right hand clutched to his chest, with no obvious external wounds. Around the scene are traces of a large hound-like creature.
The legend of the devil hound once again haunts the manor. The new heir Sir Henry is terrified. The butler refuses to speak. The doctor is evasive. The inspector is eager to close the case. Everyone seems to know something, and everyone seems to be hiding something.
Invited by his friend Dr. Mortimer, Sherlock Holmes arrives at Baskerville Manor, only for new murders to follow: a mutilated body discovered in the moor, a woman found dead in the fountain of the neighboring estate, and more cases that appear unrelated. Are these deaths connected? What truth lies behind the Baskerville family curse?
Some fear the truth. Some exploit the legend. Some hide secrets. Some watch from the shadows. Once the impossible has been eliminated, whatever remains, however absurd, must be the truth.
