Admiral Kuznetsov

Everything points to the fact that the Germans are about to start a war against the USSR. But the country's leadership denies the facts provided by intelligence. People's Commissar of the Navy Nikolai Kuznetsov realizes that in the event of an attack, all the ships assembled in the ports will be destroyed by German aviation in a matter of hours. To save the fleet, Kuznetsov will have to violate Stalin's order. But self-rule can turn into a disaster not only for him, his subordinates, but also for his family - his wife Vera and little son Kolenka.

People's Commissar Kuznetsov tries to get the Baltic Fleet evacuated from Tallinn to Kronstadt. But he meets fierce resistance from Kliment Voroshilov, commander of the land defense of Tallinn. Voroshilov refuses to recognize that the city will soon be in enemy hands, and the Baltic Fleet, locked in the port, will be destroyed. Meanwhile, the Germans are bombing Moscow and Leningrad. After a series of retreats and losses, the Soviet people need at least a small victory to raise their spirits. And Kuznetsov develops a daring plan.

The Germans are advancing on Tallinn, and will soon push through the city's defenses. At the same time, they trap the Baltic Fleet with new depth mines. The Germans' goal is to inflict maximum damage during the evacuation of the Baltic. Kuznetsov has to discover the new German depth bombs and find out on which fairway they are located.

The Germans managed to completely encircle Sevastopol from the land, the situation in the city is difficult. Not enough manpower and ammunition. Urgently need countermeasures. Stavka proposes to land a naval landing in the Kerch Peninsula. This will force the enemy to pull back some of its forces from Sevastopol, and the city will allow to accumulate forces and prepare for defense. However, the operation raises serious doubts in Kuznetsov's mind, and may prove to be a failure.

The "Road of Life", which brings supplies to besieged Leningrad, is under threat. The Germans have high-speed torpedo boats of a previously unknown modification, they sink barges with bread. Kuznetsov is assigned to discover the base of the boats and take measures. But first he has to endure a confrontation with Deputy Commissar of Defense Mekhlis.

River transports on the Volga are attacked by new magnetic-acoustic mines. The defense of Stalingrad is threatened. To help our engineers deal with the new enemy mines, Kuznetsov and Beria combine their intelligence. They have the difficult task of transferring a Soviet spy from Germany - engineer Zinaida Stern, who will be engaged in the development of new anti-mine minesweepers.

The Red Army has seized the initiative and is successfully beating the enemy. But the situation in the Baltic remains difficult. The fleet is blocked in Kronstadt and has no way out to the operational space. The Germans tightly mined the exit from the bay. The enemy has technical superiority, while many Soviet specialists are imprisoned. Kuznetsov reports to Stalin on the need to create a naval center in Kronstadt on the example of Tupolev Design Bureau - the so-called "sharashka". But Kuznetsov's idea is resented by Beria.
