The fictional detective Sherlock Holmes is not the genius he is reputed to be. Dr. John Watson (Kigsley), the real brains of the duo, has invented the world's greatest crime sleuth out of a down and out drunken and simpleminded actor named Reginald Kincaid (Caine) who is now portraying Holmes. There has been a break in at an art gallery that the pair foils. Watson and Kincaid have numerous spats, but when one of their fights over Kincaid's behavior following breaking the art gallery case escalates beyond reconciliation, Watson throws Kincaid out of the house. Kincaid nonchalantly wanders off to pursue drinking, gambling, and chasing women knowing Watson will beg for him to return. Sure enough as Watson's bid to become “the Crime Doctor” is met with skepticism by Mr. Norman Greenhough (Cook) publisher of The Strand Magazine that prints Watson's stories about Sherlock Holmes he is forced to seek out and reunite with his infamous fictitious crime-solving partner.
It seems the only thing that Kincaid is good at is never missing an opportunity to put down Inspector Lestrade (Jones), the chief of Scotland Yard who is investigating the crime but always a step or two behind the brilliant Watson. At the request of Her Majesties Minister of the Exchequer, Lord Smithwick (Davenport), they travel north to the rural countryside in pursuit of a man who worked at the Royal Mint, who has stolen the plates used in the printing of British legal tender. It turns out they are after Professor Moriarty (Freeman) and Kincaid is apoplectic when he learns that bit of bad news on their journey back to London by rail. The situation becomes very tense when Watson gets shot at the dockyard and disappears in the water. Kincaid will need to resolve the deadly mystery without the mind of Watson to figure out the solution for him.
