The Jönsson gang are a crew of lovable thieves who somehow always end up with the loot, despite being laughably incompetent. This is the sixth family comedy featuring this goofy gang. In this movie, they have a new leader, Dr. M.A. Busé, a medical doctor who has had to leave the practice of medicine. The old gang leader knew he was losing his own mental faculties, but before he went completely around the bend he designated the doctor to carry on in his stead.
