Ugly invasion. Three goblins - Lamprey, Firehead and Sevenpoint - have made themselves comfortable on a run-down campsite in the middle of the forest. But the idyll does not last. Because from one day to the next, people come from the city. Yellow-headed, his daughter Mia and her cat Teufelsblick move in with the firm intention of turning the neglected square into a paradisiacal park for vacationers. For Teufelblick that means: hunt goblins! While they are now forced to find a new, safe roof over their heads, they cannot escape the goodies that people bring: cookies, for example, or candy. They steal whatever they can get their paws on and eventually come face to face with Mia: the first and only human to ever set eyes on living goblins. How will Mia react? Will she befriend the goblins? Or will she announce that she met talking animals?
