Sherlock Holmes is dead. But since his body was never recovered from the bottom of Reichenbach Falls, imposters turn up regularly, and it's up to Dr. John Watson to disprove them. Now a telegram arrives informing Watson that three men, each claiming to be Holmes, have been committed to a remote asylum off the coast of Scotland. Watson must discover if one of the mad men is the real Sherlock Holmes. Directed by Courtney Willcut.
