When Norah is prophesied by a beggar woman that she will kill a man named Arthur Grimm on August 13th in Vienna's Prater, her world threatens to fall apart. The young journalist had actually imagined her new start in Vienna differently. But the mysterious prophecy won't let her go. She doesn't know any Arthur Grimm and the peace-loving Norah would never dare to commit a murder. But the date of the words resonates in Norah's mind: because 14 years ago, on August 13th, something happened that changed her life forever. But Norah can't delve deeper into it: the exalted performance artist Wolfgang Balder wants Norah to write a portrait of him, even though the two of them had previously clashed. But the artist wants her candid view of his work and his life. For Norah's new employer, the Viennese magazine "Neue Normalität", this offer is worth its weight in gold.
