Major is not a rank, but a nickname for Captain of Justice Mayorov. The future guard of order was raised by his grandfather, a legendary Union opera operative who always lived for work. For the grandson, everything is exactly the same: three shirts, two ties, a suit, two jackets - everything is in its place, life is planned out minute by minute. Until one fine day, Mayorov's life turns upside down: he beats up an official whom he himself arrested and brought to trial. In memory of the legendary grandfather, Major is not fired, but sent, albeit temporarily, to Tuapse.
