A temporary police chief has been appointed in the city. While Ilyina is being held hostage, Medushevsky is promoting his candidate for mayor. The balance of power in the Port is changing — the "Moscow resources" are clearly losing their positions. Meanwhile, the opera continues to search for evidence that Vershinin was not involved in Pavlov's murder and encounters an unexpected obstacle.

Jamal's men take the cargo at the port and take it to their base, where some of the boxes are loaded into another car. Vershinin finds out about this in advance, and as a result of a special operation, he manages to detain Jamal's younger brother. Khaletsky and Ilyina, who escaped from the Caucasian militants, return to the city, where they are not at all welcome. Medushevsky has to look for new ways to put pressure on both of them.

Pugachev ends up in the detention center on charges of extorting bribes from Diana. To sort out what happened, Vershinin and Gubin go to St. Petersburg to Dashkevich and find out that the USB has been deliberately digging under their department for a long time. Vershinin understands that in order to save Pugachev, it is necessary to act decisively. At this time, Davydova, having followed Komarov, becomes a witness to his secret meeting with Major Lodygin. She understands that Komarov has been using her all this time.
