It becomes swift and instructive when Holger Nilsson is forced into a raging treasure hunt across Sweden to find the seven keys to his world-famous relative Mary Diana Graaf's mythical laboratory. To his aid he has the inventor Mortensen and Mary Diana's ingenious GPS computer with pre-recorded riddles and clues written in verse. But what kind of mysterious and malicious figure is creeping into the background? The series takes you to the places where no school trips reach. It also gives you the opportunity to see how the different environments of the country differ from each other, and there will be a lot of meetings with people with different dialects.
