At the medieval castle of Runkelstein near Bolzano, an ancient manuscript is discovered. Suspected author: the German poet-singer Walther von der Vogelweide. Hardly has it surfaced when the document disappears again. PR consultant Jenny Sommer becomes an unwilling detective. Her search for the valuable manuscript turns into an adventurous chase through Bolzano, all the way to the wine village of St. Magdalena and up the local mountain Ritten.
