[2][1] Herbert and Margit Krcal are a middle-class couple living in Vienna with their young son Philipp (a great fan of Star Trek).
The mayor manages to sell the house to Herbert for a much too high price, and the Krcals start to renovate it.
The situation puts great strains on the marriage as well, and finally, Margit files for divorce.
They are informed by the local policeman that the house was built on an ancient mass grave for plague victims.
Some time later, a completely crazy Herbert takes a real estate agent hostage.
