Description:  At the center of the "Terra-X" box for children is Opa Max (JŸrgen Mai), a retired scientist who works together with his grandson Paul (Elias Kassner) on a time machine. But instead of traveling alone, the not quite functional device instead brings people from the past to the present who are lamented by Paul with questions. Themes of the first season are the old Egypt, Romans and Teutons as well as the Cologne Cathedral and other medieval construction sites.
