In rural Westphalia, Franz Berger struggles to keep his inn open. On this day, a bluff, overbearing bully, Hermann Walzer, has booked the dining room for a wedding banquet for his son Mark. There's bad blood between Berger and Walzer, so when the first course, shrimp cocktail, is off, Hermann storms out with the wedding party vowing not to pay. Franz locks the loo door, taking prisoners of the bride and Hermann's wife while he also locks the estate's outer gates, leaving Hermann and the rest outside. Walzer, a pheasant hunter, lays siege; shotguns, rifles, grenades, a shovel, and other weapons leave no one safe. Will it take death to bring these men to their senses?
Josh is about to turn 30; he's mentally retarded, and likes to play at being a vampire. His sister Nicole is 15, and dealing with her impending womanhood; middle brother Mike is the "normal" one, but in some ways the most childish - his latest conquest is Nadine, who runs the dog kennel at his security guard job. Nic is fixated on getting laid, and watches Mike and Nadine through the skylight with Josh. Josh also gets fixated on sex, though he has no clear idea what it's all about, and in particular on Nadine; to Mike's chagrin, she seems more interested in Josh than in him.
