Dr. Watson, who served in the English armed forces and was in the Afghan war, retires and returns to his homeland, in England. Since the financial situation of the doctor is very precarious, his long-time friend Mr. Stamford offers him to rent a room in the house at 221-B Baker Street, which is rented by an elderly lady - Mrs. Hudson. The second rented room is already occupied by another gentleman - the mysterious Mr. Sherlock Holmes. Holmes makes an ambiguous impression on Watson. He conducts complex chemical experiments with blood, plays the violin, has the deepest knowledge about cigar ash, London dirt and criminal law, but at the same time demonstrates complete ignorance of well-known truths (for example, the fact that the Earth revolves around the Sun), does not read fiction, as well as books on history and philosophy. At the same time, very strange visitors constantly come to Holmes, and on the table he has portraits of personalities of a disgusting appearance.
The film is set in the 1920s. Shura Sevastyanov is an aspiring journalist in a small newspaper, with two-classes of a parochial school behind him. In the spirit of building communism, he is an ardent fighter against philistinism in all its forms. He denies the phenomenon of love, believing that it does not exist and that there is only friendship and sexual desire of man to woman.
