Ein Fall für TKKG is a title shared by two German television series.
[2] The individual episodes of the series are based - with some exceptions - on the books for young people by Stefan Wolf.
Again and again, the four teenagers get involved in mysterious cases, which they masterfully solve or uncover.
Most of the time, Tim, as the leader of the group, is responsible for the approach to the different cases.
At the end of each episode, as a running gag so to speak, Dumpling always claims the success of an action for himself.
