Antje lives with her friend Schlüter, a fish, on a small North German peninsula. Here, the unusual couple experience unusual adventures, all of which generally make children's hearts miss a beat. Whether it is a ghost hunt, elevator racing or a visit from ET - Antje and Schlüter's world knows no bounds. The two friends are joined by Admudsen the penguin, who tells the most wondrous tales about his travels and brings the most unbelievable presents with him. Sigrun, the post office goose, probably makes the world's tastiest pancakes. It is hardly surprising that Antje and Schlüter love visiting her. Antje and Schlüter's adversary is Tiedtje, the fox. They are a little wary of him, but in reality, he is a quite harmless fellow, who just loves annoying other people. But he is absolutely no match for Antje's smartness and imaginativeness. Capt'n Kuck, who lives in his lighthouse, helps our friends in word and deed, should they be lost for answers. He is an extremely experienced old sea dog who loves to have a nap at midday more than anything else? Of course, we mustn't forget Arne and Bjarne, the two slightly crazy seagulls. They want to take part in everything and sometimes, what they do ends in amusing and utter chaos.
