Yuri Bragin, after a year-long business trip, where he, as part of an investigation team, was investigating a high-profile case, returns to St. Petersburg. When he returns, he learns that the current head of the First Investigation Department of the First Directorate of the State Investigation Department, Vadim Maltsev, is retiring. With a high degree of probability, it is Bragin who will be offered his place. But Yuri is not a careerist and the position of the boss is not the goal of his life. A talented investigator likes to do "live work" more. And now he is again sent on a business trip. This time in one of the cities of the Leningrad region, where two girls were killed with a difference of a week. Here, in a small town, everyone knows each other, and this complicates the search for the criminal.

Viktor Rastorguev, a police colonel, moved to St. Petersburg with his entire family. In Moscow, he crossed paths with a certain official and was forced to leave. He would no longer have been allowed to serve peacefully in Moscow. In St. Petersburg, Rastorguev became the head of the district police department in one of the city's districts. Rastorguev's family moved with him: his wife Olga and 16-year-old son Pavel. They are trying to settle into their new home, but everything in their lives is not turning out the way they would like...

The year is 1983. Yulia Morozova studies foreign languages at Leningrad University, plays sports and does not even imagine that in the very near future she will have to work in the KGB. She looks very much like the deceased wife of American spy Jim Wheeler, who arrives in Leningrad to meet with an agent working at a secret research institute. Counterintelligence agents led by Volokhov are playing a complex espionage game, intending to identify a "mole" in the defense industry. To do this, they plan to introduce Yulia into the American's inner circle, hoping that he will take the bait.
