An addiction to cocaine is a destructive passion that has ruined many lives. Even such a brilliant mind as Sherlock Holmes can’t withstand this wicked craving. An ordinary, at first glance, mathematics professor, Moriarty, becomes a fixation—an obsessive mania of a detective who has lost his balance—and Holmes turns the scientist’s existence into a living nightmare.
Trying to save his friend, Dr. Watson resorts to cunning: he tricks him and takes Holmes to Austria, where he arranges for him to be treated by none other than Dr. Sigmund Freud.
