When Willi's father is abducted and is only released for a valuable statue from his art collection, Tim is the only one who believes Willi that the police are on the wrong track. Together with the smart policeman's daughter Gaby and the highly intelligent outsider Karl, they start to investigate on their own. Against all odds the four discover a conspiracy. In the course of their first big detective adventure they grow together into a committed community, and so Tim, Klöschen, Karl and Gaby become the band TKKG.

At first, friendgroup TKKG have no idea that something is amiss when “Jugend forscht” winner Kevin behaves strangely during the presentation of his “Mind Machine” - they blame his nervousness and his unexpected termination of the speech on relationship stress with his girlfriend Nadine. But when Nadine disappears without a trace shortly afterwards, like three other children before her, the amateur detectives know that they have to help the police with their investigation.
