Willy Lorens is a successful radio idol with the hit series "Seventh Heaven". But the amount of fan mail and attention eventually becomes too much for Lorens, who suffers a minor collapse. He is taken to hospital where he meets Dr. Lovisa Sundelius, virtually the only woman in Sweden who does not admire the radio idol. In fact she despises him.
Since the program still has to air, according to the radio company, Lorens gets a vitamin injection and gets to broadcast the program from his hospital bed. Dr. Sundelius checks upon her patient, and to help him she improvise a part in the show, but does it too wildly. The next day, the newspapers headlines write about the embarrassing blunder.
To get away from it all, Willy Lorens buys a bus ticket for a trip through Europe with Italy as the destination, but it just so happens that Lovisa Sundelius also has a ticket for that same bus ride. Along for the ride is also Lovisa Sundelius' incredibly dull fiancé...
