Upstart detectives Sherlock Holmes and Dr. Watson are on their first case. Their client, a young H. G. Wells, has hired the novice detectives to find a manuscript by Arthur Conan Doyle. Hiding from their angry landlord, Holmes and Watson duck into Wells’ time machine, push a few buttons, and soon find themselves in the 21st century. They end up at the Freudly Institute, where they meet many famous historical people. Actually, these are patients at the institution with delusions that they are these famous characters, which explains why Holmes is treated like just another patient. They think Watson is his doctor who’s just playing along. When the body of an unknown victim is found on the grounds of the institute, Holmes sets out to uncover the clues while trying to prove that he is the real Sherlock Holmes.
