Conni is excited. Her parents are travelling to Uncle Albert‘s with her brother Jacob. Conni would have loved to go with them, but then she would miss Semire‘s birthday party. Of course, Conni and Mau the cat don‘t stay at home alone. Granddad Willi has come, and Anna and Simon are even allowed to have a sleepover.
But then an injured crane lands in their neighborhood and needs their help. It‘s not just the injury that‘s bothering Crane Klaus, but also the stuffy neighbor Mr. Oswald, who thinks his immaculately tended rose garden is in danger. It‘s a good thing they have the support of animal rights activist Renata and policewoman Selena. Much to the displeasure of tomcat Mau and Anna, everything now revolves around the huge, proud bird.
Will Conni and her friends still manage to get Klaus to fly south with the travelling birds in time?
