Kovak quarrels with Ilyina and plans to flee the country without her on a ship carrying out arms smuggling. Isakov instructs Zharov to kill Kovak. The operas who found out about Kovak's plans also go to the port... Having turned all the arrows on Kovak, Medushevsky, it would seem, again escapes justice. But Vershinin and his team are not giving up, especially since Khaletsky agrees to cooperate with the police.

Jamal and his men attack the Ambulance, hoping to arrange an escape for his brother, but Gubin, who arrived in time, repels the Caucasians, and they die in a shootout. Medushevsky convinces Isakov to get rid of Kovak. Suddenly, Khaletsky kidnaps Vika in a cafe — the guard recognized him as a fugitive prisoner, and in order to leave, he was forced to take a hostage. Vershinin, fulfilling the conditions set by the kidnapper, goes to meet Khaletsky alone.

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.

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.

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.

Ilyina's driver was killed, and the woman was abducted and hidden outside the city, the criminals injected her with truth serum and recorded on camera a confession that she was not going to fulfill her election promises, but called voters cattle. Medushevsky gives the scandalous material a go, and Ilyina's political career is crumbling before our eyes. Kristina tells Vershinin that they want to kill her, and he is ready to help her in exchange for testimony against the criminal.

The investigation does not have enough evidence to prove Pavlov's guilt in torturing Gubin. Vershinin is forced to let him go. Pugachev, outraged by the fact that the killer is on the loose, gets drunk in a bar. It is there that Andrei encounters Pavlov again. Upon seeing the colonel, the criminal begins to insult him. An enraged Vershinin drags him outside. Pugachev, who arrived at the noise, discovers Pavlov shot dead, and Andrei lying unconscious nearby.

The head of security finds secret data from Kovak's email in Gubin's phone. Under torture, Gubin is ready to confess not only that he is Vershinin's agent, but also to what he did not commit. After learning about the torture, Vershinin organizes a raid on the port.

Vershinin is investigating a shootout on the road in which Gubin was wounded and five people were killed, but for some reason Masha, a witness, was left alive. He forbids her to tell anyone that she was at the scene of the shooting.

Vershinin's daughter does not get in touch. The group and all the hero's affairs are going to be transferred to Major Ladygin. Businessmen come to the city and start a war for the post of head of the port. And Masha's suspicions about who the "mole" is from the department are confirmed.

Medushevsky's wife finds out where Yura is being hidden and informs her husband about it, hoping that he will let her go. He gives instructions to kill Nikitin. At the same time, Lupanov, a top manager of the Moscow Resources Corporation, is found dead in a hotel room. Vershinin suspects that this is the work of Serge.

The bartender randomly manages to stop another attempt. In an attempt to bring the girl to her senses, the man fails to catch the attacker. But now the police have a description and a rough portrait of the rapist, in which Masha recognizes her brother. Meanwhile, they want to remove Vershinin.

A girl was raped and killed in a port. This is the third episode in a short time. Diana almost becomes his new victim, but the Pug and Pugachev arrive in time to save the girl. Now the operas have a living witness who can identify the perpetrator.

Medushevsky's wife is seriously scared: she is sure that her husband wants to kill her. The woman's fears are not in vain — soon she is attacked by three bandits. It is only thanks to Vershinin, who came to the rescue, that she remains alive. After that, Andrey hides the woman at home.

Riot police storm the country house where Yura is being held. However, Khaletsky has nothing to charge, except kidnapping. Vershinin understands that more powerful forces are involved in the attempt on Yura and the murder of Gleb Borisov. Meanwhile, Medushevsky is released directly from the courtroom. First of all, the lawyer contacts his wife, who once contributed to his arrest.

Ilyina gives Vershinin 24 hours to find Nikitin. Meanwhile, Andrey's team begins searching for and detaining everyone who produces and sells drugs in the city. All those caught point to Khaletsky. Vershinin realizes that it was he who took Yakovlev's place and is now trying to regain control of the port.

The investigation into the assassination of Nikitin and Borisov continues. The evidence points to the serious training of the attackers and their connection with the top army leadership. Yura is also not going to sit idly by and wants to take revenge on his godfather's murderers on his own, but he does not have time — Khaletsky kidnaps him.

Protovoy mayor candidate Alexandra Ilyina gets acquainted with Vershinin. She plans to run her election campaign together with the Interior Ministry and is counting on Andrei's help. To gain his support, Ilyina invites him to a meeting. Meanwhile, Yura encounters a certain Khaletsky, who demands to be allowed to use the port, and, having been refused, begins to threaten Nikitin.

Vershinin has almost recovered from his injury and is ready to return to service. But before he can leave the hospital, an attempt is made in Portovo on Gleb Borisov and Yuri Nikitin, who continued his father's business after his death. The Jura hinders many of those who claim ownership of the port, including the Moscow Resources Corporation, which Medushevsky, who is under investigation, is counting on to support.
