Uuno goes with his wife to spend summer holiday to their villa in country, studies playing of the violin in a correspondence course and constructs an own violin with do-it-yourself-method, but quits his career when he perceives that takes his free time too much and comes back to live the life "in the shadow of a fridge". In the start scene of film a priest (Ere Kokkonen as voice) says in the Uuno's weddings that his complete name is Uuno Eero Turhapuro, whereas it's in the all later Uuno-films Uuno Daavid Goljat Turhapuro.

It is the first anniversary of Uuno and Elisabet. Uuno has placed a bet with his friend Härski-Hartikainen a year ago, that if Uuno can take just one year of marriage with Elisabet, Hartikainen will treat him a festive dinner. However, Hartikainen buys a lottery ticket for Uuno, who agrees to deduct it from his debt – and the festive dinner is reduced to a can of milk and half a sausage. As it happens, Uuno becomes the lottery winner of 1.5 million marks, only to soon realize he doesn't own a single penny yet.

He buys a raccoon fur, leopard swimming trunks and a couple of Mercedes-Benzes. Women begin to fancy Uuno and so does his father-in-law. As time goes by it is revealed, though, that Uuno is not actually a lottery winner, and so he has to escape the anger of others to Härski's car repair shop.
Uuno moves in flight cargo to Helsinki for the search of a rich, beautiful wife.
