Driving teacher Carola, called "Charley", does not stand up to her students' constant attempts to approach each other and quits her job. In order to gain some distance, she takes the opportunity to watch her friend Lilo on their dog, the two parrots and her apartment, while Lilo is on vacation. But here too, unloved admirers have to be swept away, as Lilo earns her money as a playgirl. However, "Charley" has got a good tip from her friend: as soon as a man becomes too intrusive, Hauswart Pinkus pretends to be a "Captain Tressblekken", who quickly drives visitors away. But when the really existing uncle Tresblekken shows up at "Charley", the chaos is no longer averted.
