In the 1930s, Sherlock Holmes (Arthur Wontner) takes a holiday by visiting his old friend, Sir Henry Baskerville (Lawrence Grossmith). Holmes' vacation ends when he and Watson suddenly find themselves in the middle of a double-murder mystery; they must find Professor Robert Moriarty (Lyn Harding) and Silver Blaze before the horse race, and bring the criminals to justice.

Critical reception
In a retrospective review, TV Guide wrote that the film "suffers from too slight a plot stretched out to feature length. Wontner is good in his final portrayal of the great detective, and the film does have some interesting moments; but on the whole this is lackluster Holmes, an all too elementary case."[2]
