Nadya, who works as a librarian, has long forgotten about meeting the fashion model Lera at a clinic. But Lera unexpectedly calls and invites Nadya to a fashion show. Yet instead of the expected stylish outfits, Nadya finds the body of Lera’s friend Sonya. The girls’ manager, Marat, immediately accuses Nadya of murder—but then changes his attitude when he sees her as a suitable candidate for advertising dog food needed by a foreign partner. Nadya came to sign a contract, but in Marat’s office she finds his dead body. Now the police is seriously interested in the girl, and the situation becomes critical. Nadya’s only salvation is the help of her longtime friend Dima Poluyanov.
