The conceptual artist Valentina Eberlin is currently in the process of realizing a spectacular installation project in Kitzbühel. However, she is unable to complete it after she is killed in the gallery of her married lover Henrik Weigel. Eberlin's uncle Ernst knows of the victim's strange connections to the industrialist Roschmann family. Does their influence extend to the deadly elimination of Eberlin and what reason would they have from the past to do so? Or did Weigel's family have a hand in it and were out for revenge?
