When she got a job at a detective agency, Vasilisa Selezneva dreamed of taking part in real operational work. But in reality everything turned out to be much more prosaic. Clients appeared rarely and turned out to be completely uninteresting: as a rule, these were husbands or wives who felt that their companion was playing a dishonest game, or, simply put, walking to the left. So a new client, looking like a sad camel, reported the disappearance of his wife, whom he suspected of infidelity. Vasilisa is so tired of getting involved in yet another family squabble, but she takes up the investigation and reveals the secret of her unfaithful wife, and also brings her husband and his mother to light.
