Lasse is a car salesman who has vowed to never get married. He wakes up hung over one morning with a wedding ring on his finger and a nude woman in his bed.

The story bases on four Finnish brothers, nicknamed 'the Eura Daltons' who received nation-wide notoriety for tearing gas pumps apart when they needed cash.

In the 1970s, Turku City Theater staged an adaptation of Aleksis Kivi's Seven Brothers, directed by Kalle Holmberg. The premiere was in 1972, and performances continued for three years. The play was the biggest theatrical event of its time and a huge success with audiences. The brothers were played by the stars of the decade, with music by Kaj Chydenius. The TV movie was recorded from two public performances and close-ups were edited in.

The TV film depicts the loneliness that follows divorce.

Uuno Turhapuro is a lazy man who abhors manual labor, but has the ability to talk himself out of any sticky situation, usually with his long-suffering wife. In this, his first feature film appearance, Uuno embarrasses his wife in public, tricks his best friend, accidentally goes on a diet, and becomes a famous violinist.

Uuno is unemployed and his friends try to arrange a job for him. With his imagination, though, and the help of Härski Hartikainen (Spede Pasanen), he somehow manages to avoid all work, until he becomes what he has always dreamt of being - a film star. Uuno's father-in-law has other plans for his occupation, though: since Uuno knows the Dandelion, he has potential for a professor of botany.

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.

Uuno disguises as an old man and infiltrates a nursing home for rich old people, where his father-in-law also lives. The ever-hungry Uuno is seduced by the table groaning with food, but as it happens, he never manages to be there at dinnertime. Meanwhile Sörsselssön enters Uuno for a TV competition named This Is My Life, where contestants tell about their life as viewers vote them either to continue or out of the show. The nursing home elderly watch on TV as Uuno tells the show's host his life story.

Uuno moves in flight cargo to Helsinki for the search of a rich, beautiful wife. He buys elegant clothes for eight marks from an estate auction and in two weeks becomes the most pursued bachelor in town, charming all the women. He also starts as a waiter in Vaaleanpunainen sika (Pink Pig), which starts the first quarrels between him and his father-in-law.

Uuno Turhapuro is searching for a job and takes a correspondence course in tour guiding. Eventually he gets a job in a small travel agency and takes a group of Finnish tourists to Marbella, Spain. Unfortunately Uuno's father-in-law Tuura is in the group, too, with his wife and daughter, Uuno's wife Elisabet. Tuura tries to get a signature to an important paper from a minister who's having a holiday in the area. Meanwhile, Uuno just relaxes and enjoys the sun.
