Henry Denninger is team boss of the Koonan Cars racing team and is determined to win the TransAfricana Rally with his team this year. Claire Leonhardt is the head of an environmental protection organization in Freiburg and is fundamentally opposed to motorsport as a climate killer. Either of them could pursue their goals undisturbed if Henry hadn't taken it into his head to complete a training phase in the Freiburg area of all places, where his daughter Sofia lives.

Three women decide to turn the tables and fight back: Henriette, the feisty journalist of a women's magazine, the editor Anna and the beautiful saleswoman Sigi, together deceive the head of the publishing house by creating a fictitious author.
