World ex. ChinaMarta-Maria lives with the very wise tomcat Iwan Iwanowitsch in her father’s house. Her father is fat and snugly, but sometimes overstrained with his imaginative and headstrong child. Whenever Marta-Maria pushes things too far and the father is at his wits’ end he calls his friends: the very intelligent professor Tripepan, who has a solution for nearly every problem; Two-zero-seven, an author, who writes stories for the children’s program and adorable Carmen Tootle, who understands little girls. One of them always follows Marta-Maria into her cosmos of imagination und helps her to return safely into her everyday-life.
