Sherlock Holmes and Dr Watson are hired to keep a man safe from a legendary family curse on the bleak moors of southwest England. They investigate a chilling tale -- a monstrous hound said to haunt the Baskerville family across the centuries. In this episode, Watson keeps a wary eye on Sir Henry, the last Baskerville heir, while Holmes uncovers unsettling clues in the shadows. The hound only ever leaves footprints but its howls echo through the fog, and a silent figure watches from afar. A compelling mystery where logic and reason go head-to-head with fear and fog in the night.
