In one part of the documentary, son Staffan Oldsberg and friends Lasse Kronér and Lennart "Hoa-Hoa" Dahlgren embark on a "På spåret"-like journey through Europe, directed by Ingvar Oldsberg himself. Before his death, he had secretly left a letter and an accompanying package with a law firm in Gothenburg.
A year after the father's passing, son Staffan Oldsberg received this unusual inheritance. In the letter, Ingvar Oldsberg wrote, according to Aftonbladet, "travel is life and you should do it now". The package contained notes with "På spåret"-style puzzles that led the son and friends on a very special journey.
When Lasse Kronér was contacted by SVT for participation in an upcoming documentary about friend Ingvar Oldsberg, he told them about the package. To Aftonbladet, Lasse Kronér says that SVT became "wildly enthusiastic" and wanted to follow the friends on their journey. Through various puzzles, the friends then made their way to different cities. Staffan Oldsberg tells Aftonbladet that the journey became "crazy and magical".
To be broadcast in two parts on SVT on September 1 and 8. The first part is called "The Unknown Inheritance".
