The TV series "Entrance to the Labyrinth" is based on the novella "Medicine Against Fear" by the Vayner brothers. Two Soviet scientists invent a miraculous drug that completely eliminates the feeling of fear in test subjects. The drug falls into the hands of the mafia, who use it to manipulate police officer Pozdnyakov. Under the influence of the drug, he hands over his service weapon and identification, incriminating himself. Investigator Muromtsev takes on the case, but he is skeptical of alchemical experiments and magical elixirs.
