Tobias Totz is a very special zookeeper. He is full of understanding for his animals, and they all love him. His best friend is the lion, who dreams day and night of falling in love. As there are no lionesses in the zoo, Tobias decides to fly to Africa on the spur of the moment, to find a girlfriend for the lion. However, this is not as easy as it sounds. Nasty animal-collectors have lured lots of animals, including Lea the lioness, into traps. And although Tobias manages to free her, the animal-collectors are hard on their heels. All kinds of adventures can - and do - happen before the lion and Lea are up in the clouds, sharing a rosy future together...
