In the dawn, a rowboat drifts on the mirror-smooth St. Moritz Lake. Inside is the body of Anastasia Maranta. Her father, Rudolfo Maranta, the uncrowned king of the Engadin jet set, promises a reward of one million francs for anyone who can solve the mystery of his twenty-four-year-old daughter's death. The justice system assigns Alpine police officer Corina Costa to the case. The nature-loving officer, who is also a mountain farmer and lives with her marmot Fred and other animals above Pontresina, enters a world completely foreign to her, filled with material wealth and false smiles. The deeper she delves into this sphere, the more dangerous it becomes. A manhunt begins amidst the Engadin mountains.
