Katya is an irreplaceable employee of the Investigative Committee. Despite the modest position of secretary, she often helps with investigations and can talk to even the most unsociable person. The personal life of the heroine is also closely connected with the organization: Oleg's son works as an investigator, her lover Eugene is a lawyer.
Her life runs like clockwork. But a string of unexpected events knock Katya out of her rut: her beloved boss resigns, her personal life suddenly breaks, her son behaves strangely and is obviously hiding something. And Vasily Gromik, with whom she once had a close relationship, becomes the new head of the SC.
The heroine is at a dead end. After all her 25 years of work as the secretary she has learned to smooth out any conflicts and solve the most difficult problems. All except for own.
