Wolle and Horse want to help the girl Emma and her grandpa. Verena Winkel from the youth welfare office wants Emma to live in a children's home instead of with her grandpa. Of course, this must be prevented! Wolle builds a time machine with which Emma, Horse and he undertake three adventurous journeys into the past: to the Vikings, to the early 19th century and to the Lapuna Indians.
