At a ballroom of a hospital charity party in Budapest, the successful United States lawyer Jonathan Harker (Hardy Krüger Jr.) suddenly proposes to his girlfriend Mina (Stefania Rocca). He wants to marry her within the week. Their friends Lucy (Muriel Baumeister), Quincy (Alessio Boni) and Arthur (Conrad Hornby) have been invited by Jonathan and have just arrived for the wedding, all without Mina's awareness. Meanwhile, they meet the promoter of the party, the psychiatrist Dr. Seward (Kai Wiesinger). Later in the same night, Jonathan is called by a rich client, Tepes (Patrick Bergin), who hires him to prepare the inventory of the wealth of his uncle, the count Vladislav Tepes (Patrick Bergin), in Romania. Jonathan travels to the Carpathian Mountains in his Porsche, has an accident and finally arrives in the count's old castle.
