The scatterbrained archivist of Cologne Cathedral is sent to Africa to retrieve the largest diamond in the world, on which the cathedral once rested and whose absence is now causing the foundations of the building to sink. In his wake, shady characters appear who are also after the precious stone. But there are also helpers who are well-disposed towards the adventurer against his will.
