Anna isn't particularly interested in boys. Her little brother Raoul is bad enough, so she doesn't need an older member of his sex for her happiness. One day Raoul catches a frog. Anna just manages to save the little green frog before he can harm him. But what should she do with him now? Should she throw him against the wall, like in the fairy tale? Or kiss him? But before Anna can decide, the frog beats her to it. And simply kisses her. As if that wasn't cheeky enough, Prince Dietbert von Tümpelberg suddenly stands before her, a prince who was enchanted a thousand years ago and can only be saved by the love of a virgin. Well, he can wait a long time, thinks Anna. But her frog prince is actually quite cute...
