Hubert und Staller - Die ins Gras beißen (2013)

Hubert and Staller find the first body in the forest, the second practically falls into their laps. The trail leads to a retirement home, of all places. The old men finance their retirement by growing cannabis, and they have also been blackmailed, but that doesn't make them murderers. Or does it? Meanwhile, precinct manager Girwidz is hoping for a promotion: his old boss has announced his arrival. However, the police director is in Upper Bavaria for a completely different reason.
