200,000 fledglings have just been delivered in Cairo. The plane is ready to take off again for the onward flight to Nairobi, where the crew wants to spend a few days relaxing before returning to Germany. But then it turns out that apparently only 199,999 fledglings have been unloaded. One of them is still on board and beeps desperately behind the wall paneling. It is rescued and the co-pilot decides to give the fledgling to his son as a Christmas present, but it is surprisingly difficult to supervise a small bird. In fact, Harry - that's the little one's name now - disappears and can only be found and rescued again with a lot of effort and after several adventures.
