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.
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.
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.
