Greed and murder, a family drama, and a thousand-year-old secret in the mountains. When Max Hüttinger, a good-for-nothing suffering from chronic money problems, offers ancient parchment pages that have been in his family for generations at an online auction, disaster strikes. Not only is he acting against the wishes of his hot-tempered father, but several rival bidders also appear in Garmisch-Partenkirchen, sensing that the Latin texts hold the key to an ancient secret hidden in the Karwendel mountains. After the parchments change hands, one of the men is found murdered in his hotel room one morning. Commissioner Ignaz Greibl begins the investigation. At the same time, climber Henning Franke observes strange occurrences at the foot of the Kreuzwand during his climbing holiday in the Karwendel.
