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.

Egon and the gang are hired to stage a robbery of an antique Chinese vase for an economically challenged baron. Naturally they fooled, which infuriates Egon. The gang tries to get back at the baron by switching the vase with a cheap Hong Kong copy. One attempt is made during the barons hunting party, where Egon ends up being bricked up in the catacombs. In another attempt, the gang has to coordinate breaking through several walls at The Royal Theater in Copenhagen with the "Elverhøj" overture.

After twelve years in the US, Kirsten returns home to her father with her American husband and their eleven-year-old son. Her father is a tough and cold businessman with whom she has never been on good terms. The couple soon separate, and Kirsten meets a former friend. Her father dies just as he is beginning to develop a good relationship with his grandson.

The oldest ship in the fleet, Martha, and her jolly crew, must race Harald and win, or it's the scrappers next.

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 escapes from the psychiatric ward, where he has been incarcerated since the gang's last coup. Keld and Benny pick him up, and when Egon, as always, is planning the big heist, the Olsen Gang is once again on the move.

The Olsen Gang has finally made it. They are in Mallorca, having fulfilled their dream. Almost, that is. They don't have any money, so Egon has to open a safe at a restaurant to get some. As usual, however, Egon ends up in prision. When they return to Denmark, he has a new plan.

Some criminal EU ministers plan to turn Denmark into a gigantic fair ground and holiday paradise. Egon gets his hand at some important documents which could both make him rich and take care of Denmark's future.
