Backwoods Crimes - Vienna Rollercoaster

Major Vilser is a policeman with the State Office of Criminal Investigation who is a bit too close to the Viennese underworld, and in the wrong kind of way for someone in his position. He has forgotten that his son Florian wanted to spend Christmas with him, to finally spend some quality time with him. First of all he gets allocated young Voralberg policeman Matthias Tschofen, then his son suddenly arrives at the door.
Vilser makes his rounds through the underworld of Vienna. Being so close to it hasn't done him any harm so far, because he's part of police commissioner Elsbacher's inner circle. But Lieutenant Colonel Gerlinde Zach from the anti corruption agency is trying to bust the men's corrupt ring.
