The first of 14 Olsen Gang films presents us with Egon Olsen, head of the gang, and his friends Benny and Kjeld, who want to become the best known gang in Denmark and eventually Europe by stealing a famous Bavarian work of art currently displayed in a Copenhagen museum. Although Egon's plan works out fine, there is only trouble ahead for the little gang.

The Olsen gang in Jutland. Ones again Egon Olsen has a plan when he gets out of Vridslose State Prison. He has found out that the Germans left a large sum of money (in American dollars and gold bars) in one of their commando bunkers, when they were defeated in 1945; the only problem it's in Jutland. Egon, Benny and Kjeld "appropriate" a car and drives to Jutland along with Kjelds wife and child Yvonne and Borge. They look forward to fooling the the people in Jutland, but of course, things don't go quite as planed. It ends with Benny, Kjeld, Borge and Yvonne sitting in the train back to Copenhagen, were they are overtaken by Egon in his car on the road next to the track. This is the last time the Olsen gang goes to Jutland.

Egon and his two cronies managed to sneak a fortune with them to Spain. Here they live a life in a whirl of pleasures, but they are not truly happy. While Egon always has the money chained to him, Bøffen still manages to steal them. Egon ends up in jail once again, and when he comes out, he has a brilliant plan.

A good looking female social welfare worker makes Egon Olsen forget about crimes for some time, but when an American gangster breaks into a local bank and the police think its Egon's work, he has to get back to work to prove he's innocent.

Egon plans to exploit knowledge gained during his latest term of incarceration. By stealing the unmanipulated financial records of DanInvest he obtains the majority of the stocks in the department store Magasin du Nord, just in time for their closing sale. The attempt to get the red suitcase that will save the day they rob the main vault at the EEC headquarters in Brussels and end up hijacking a tank.

The family Gyldenkål is actually called Iversen, but have changed their name, after numerous problems with the IRS, loan sharks and employers. Using clever scams, the family builds up a reputation as a wealthy and respectable part of society.

The second film in the series about the enterprising Gyldenkål family. Now the family has climbed to the top of the social ladder, but unexpected demands from the tax authorities mean that a forced auction is imminent. So they embark on their biggest scam yet: defrauding Fidusbanken.

The final film in the Gyldenkål trilogy. Following a financial downturn, Charles Gyldenkål decides to run for municipal office. After an unconventional election campaign, he is elected to the city council and becomes the deciding vote in the mayoral election.

When Egon Olsen gets out of Vridlose State Prision once again, his friends Benny and Kjeld do not want to know about his new ingenious plan: they are actually WORKING in a shop! Thus, he has to think of something else to get his hands on the money of some international gangster.

As usual, Egon has an ingenious plan. And, as usual, it works just fine until one of the gang members makes some kind of funny error. This time, however, even Egon's life is in danger, for some international criminals try to get rid of him by throwing him into a container filled with acid.
