Christmas is coming up and Florian, barely twelve years old, this time has only one wish: He wants to finally get to know his biological father. But that is not so easy, because Major Josef "Seff" Vilser, a hard-nosed criminal official, lives in far-off Vienna and is not really eager for the fact that this year not only Christmas, but this time his biological son is also at the door , The passionate womanizer and relationship figurine Seff has never denied his paternity, but hardly ever lived. But Florian does not let up and finally persuades his mother for the Christmas trip to Vienna. And a little later father and son are actually facing each other. What follows, however, is a rather turbulent, sometimes almost ludicrous holiday week in the wintry city. The fact that this week but some long-smoldering conflicts in the Vienna underworld ignite almost explosively and two violently competing red light bosses want to dispose of each other, does not make for a relaxed holiday mood.—alabalan
