The Hound of the Baskervilles

Sherlock Holmes (Basil Rathbone) is intrigued by a centuries-old legend in which every generation of the wealthy Baskerville family is eventually killed by a monstrous hound. Suspecting there is more to the story than meets the eye, he sends Dr. Watson (Nigel Bruce) to the estate to investigate. Sir Henry (Richard Greene), the only Baskerville left, is grateful for his help. But when a crazed convict escapes and footprints from a beast are found, Baskerville wonders if Watson will be enough.
