A world in the distant future is threatened by a terrible plague: dragons have afflicted the realm. The dragon hunters have made it their mission to catch the dangerous invaders. One evening, a mother dragon and her chicks move onto the roof of Jeanneline's "Tavern zum Snoring Drachen". Gwizdo and Lian Chu, who are about to set off on a luxurious assignment, are now stuck. As soon as they open the front door, the mother dragon will attack. Therefore, Gwizdo negotiates a contract with Jeanneline: They chase away the dragons and Jeanneline forgives all their debts.
