Investigator Masha Shvetsova is sure that the hardest thing to solve is the kidnapping of a person. That is why she took on the case of the kidnapping of a young businessman, which is already being investigated by the city prosecutor's office. The case is absolutely “silent”: the young man had absolutely no enemies, conducted the company’s affairs carefully, and was not associated with crime. Complete absence of any clues! Masha has very little time to unravel this “Gordian knot”: the faster she comes to a solution, the greater the chance that the businessman is still alive.
