It is the summer of 1968 and also in South Moravian Pálavice appear political clashes. The so far peacefully farming Unified farmers' cooperative starts splitting. Some of the farmers have found the cooperative called Vidrupa and want to deal with wine in private trade. Michal Janák, chairman of the farmers' cooperative is a deliberate man and refuses the latent return to the capitalism. As an excellent farmer he continues preparing planting out new vineyards. His adversaries do not agree - the returns will come many years later. Jozka Hrdlicka, an émigré, notices on the Austrian TV the interview with the representatives of Vidrupa and decides to visit his native village. The new suit and the hired car transform the bankrupt and criminal to the successful businessman with wine.

Third wine session, this time with a computer. The film was made in direct relation to the audience success of the previous two: "Stormy Wine" and "Ripe Wine". In the comedy-oriented story, the computer is an important actor, around which all the events actually revolve. It is reliable, powerful, but unused. Its future lies in the hands of those who do not yet know how to use it.

A loose sequel to the 1976 comedy Stormy Wine. The screenwriters and the director recreate on screen a number of characters from the South Moravian town of Pálavice, characterised by their different attitudes and approaches to work and private life. A number of serious issues touching on the times emerge around the story of the con man. The fundamental dispute between the vice-chairman Janák and the chairman of the merged cooperatives ing. Urban, as well as the satirical theme of illegal machinations and bribes, are undoubtedly of general validity.
