A Federal Security Service captain Oleg Rezvov (nicknamed Frisky) and a FSS senior lieutenant Artem Atalyants (nicknamed Italian) receive a new task: they must intrude the criminal grouping of one Black Sea city, gather information and prepare for its capture. Frisky and Italian open a nightclub and an illegal casino in a mansion.

A dangerous visit of the bandits turns into a meeting between Frisky and his old comrade Resin. Now he is the brigadier of the part of the group headed by Barik Kubanyan, nicknamed Cuba. Resin is ready to present Frisky and Italian to Cuba. Cuba gives the heroes the first task to check their reliability - to squeeze money from one businessman.

Alla, messenger from the Center, gives Frisky and Italian information about the huge thief gathering in the city and the intentions of the police to perform an exemplary takeover. Heroes manage to come up with a legend and offer Cuba a plan that allows not to cancel the meeting and to outwit the "cops". Cuba listens to their advice - and everything goes according to plan.

Italian begins a risky romance with Kira, Cuba's daughter. Kondratenko threatens to arrest Frisky and Resin, but he has no real clues. Glotov, the head of the Cuba's security service, doesn't trust Frisky and Italian and wants to disclose them. Glotov communicates anonymously with Kondratenko and skillfully provokes him to abduct Vera. Frisky, Italian and Resin rush to save the girl.

Cuba's wife has some kind of secret, Cuba's son has problems with drugs, and the relationship of his daughter Kira and Italian is becoming too serious, Glotov accepts Cuba's daughter's romance, and Cuba is forced to take emergency measures. He sends Italian and Frisky to Abkhazia to look after the winery, where things are not as good as reported by Abkhazian Cuba's partners.

In Abkhazia, Italian and Frisky reveal a series of deceptions, thus proving to Cuba that the wine industry and the cunningly designed plan for the transportation of bottles across the border, Cuba's partners use to transport drugs. Cuba is planning a terrible revenge.
