Stig-Helmer Olsson isn't the fashionable jet-set type, but, for the first time in his life, he's going to travel abroad. He chooses a trip to the Canary Islands over Christmas. Before leaving, his doctor asks him to bring a package to a friend of his. Without Stig-Helmer knowing it, the package contains 50,000 SEK, which is illegal to bring out of the country. However, Stig-Helmer's bag with the package disappears at the airport. Dr. Levander's friend believes that Stig-Helmer has stolen the money and is anxious to get them back.

Vanheden and Dynamit-Harry, together with Harry's fiancée Doris, are in Mallorca while Sickan is still in Stockholm. However, Wall-Enberg wants him to do a break-in at Cardinal Wulka's in Mallorca. He can't resist this and goes down there. However, Wall-Enberg can't be trusted. Sickan is fooled, caught and put in prison while waiting for transport home to Sweden again. After Vanheden and Harry have broke him out of jail, he's, naturally, set on revenge. 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 coup being planned against the cathedral in Parma.
