Horst Moltke dies in the precinct just after whispering to state attorney Bannenberg "Martin Walden must inherit all!" '*Widow Simone Moltke is appalled by his death, as turns out poisoned, but mainly that the inheritance falls to their manipulative relational therapist. Failing to find a suitable female cop partner to go undercover, Heldt and Ellen enjoy playing 'troubled spouses' more then the proper date they never had. While Heldt and Ellen spy on staff and fellow couples, Grün and Mario examine Walden's session videos. The place proves infested with lies, infidelity and even drug trade.
