Munich law school students 'repetitor' (academic tutor) Andreas Lechfeld was fatally stabbed in a park. His wife, a successful attorney, sees no ground or enemies. The team soon finds he has a row with a student who couldn't pay and was unwilling to settle it 'in kind', actually on tape. Lots of client students were frustrated as even with the expensive help many fail the bar exam, including Robert Huber, the most ambitious of the three 'referendaries' (deputy repetitors), who pretends to his parents already to have passed but actually the while firm is in dire financial straits.
