As always, Sickan has come up with a new plan. This time he wants to rob the IKEA furniture store. During their nightly break-in Sickan discovers that the store is used as a secret smuggling central for sending American computers to the Soviet Union. The computers are picked up by Soviet submarines sneaking into the Swedish archipelago. Naturally, it is their arch enemy Wall-Enberg who is behind all of this.

After years on the run, Sickan reunites with Vanheden, Harry and Doris for another coup. The plan, timed to the smallest detail, is to steal a complete T-Rex skeleton from the Natural History Museum and sell it to the unscrupulous businessman Wall Enberg for 320 million SEK. However, they have not counted on Rigmor Gren, an aged policewoman, obsessed with the idea of ​​bringing Jönsson to justice before she herself retires.

Vanheden and Dynamit-Harry, together with Harry's fiancée Doris, are in Mallorca while Sickan is still in Stockholm. However, Wall-Enberg talks him into doing a break-in at Las Palmas cathedral in Mallorca. Once persuaded, he can't resist the temptation and travels to Mallorca as well. However, Wall-Enberg obviously can't be trusted. Sickan is framed, caught and put in jail. While being escorted home to Sweden again, Vanheden and Harry sets up a plan to break him free. Sickan, once free, wants payback. The gang discover that an antiques dealer called Germann has something to do with the whole thing and that she's also collaborating with Wall-Enberg. The gang then decide to take a closer look at her and her antiques and they discover that there's a heist being planned against the cathedral in Palma.

Vanheden and Dynamite-Harry are approached by Sickan's grandmother and Sickan's younger brother Sven-Ingvar. Their evil nemesis Wall-Enberg are planning to steal billions of euros of the European Union's grants to culture. The grant of 350 million kronor, paid by an Italian bank acting as intermediary, equals 60 billion lire but through assistance of a Sicilian "businessman", this sum becomes 60 billion kronor when transferred. The money is to be transferred to a large number of bank accounts, and the account numbers are saved on a floppy disc that the Jönsson gang is trying to steal.
