The fourth part of the Soviet TV series based on Arthur Conan Doyle's stories about Sherlock Holmes. The film was shot based on the story "The Sign of Four" and the story "A Scandal in Bohemia".

During the investigation of the Agra treasure case, Holmes and Watson recall another case that Holmes had investigated earlier. The King of Bohemia comes to Holmes under a false name, who behaves somewhat arrogantly at first, and then plaintively asks for help.
