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. Mister Tossavainen arrives and offers to finance Uuno before he actually gets the jackpot. Thus Uuno gets to live a rich live on credit. 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.
