Two leading characters, Andrey Andreevich and Oleg Borisovich are both retired colonels. One of them headed a local KGB department and the other a local police station. But time came to retire and hand over the life-work to the younger. Though quiet regular life is not their cup of tea... A brutal murder of a famous businessman and police's inaction make the retired officers remember their field service skills and declare war to the local crime groups. They skillfully manipulate events and cause clashes among crime groups. As a result the latter start destroying one another. When the State Office of Public Prosecutor learns about the situation in the city, they knowingly send there a seemingly hopeless detective, Elena Reshetnikova. However, Elena proves to be a truly professional investigator.—FILM.UA
