Hiking with his ex Carola and her daughter Mia (9), Markus stumbles on mountain guide Robert, who made a fatal fall, pushed during a struggle. Rookie Schladming police commissioner Jessika Pollath wants to prove herself in this case, grudgingly assisted by fat constable , but the blood graces aren’t Robert’s. His weekend hiked clients, couple Tilmann and Sonja, are missing, so the rescue team starts searching too. Tilmann actually blames Sonja for his head injury with a rock while fighting with her lover Robert, and his condition worries dauntingly as they seek a way town, lacking phone reach, so he confides his radio-traceable watch to the river. While the search continues, Carola makes a really bad, deep fall, with unsure prospects even after helicopter evacuation and hospitalization, so she asks for a lawyer to draw up papers so her very single ex Markus, who was neither consulted nor feeling qualified, may step in as Mia’s ‘father’ if she dies, his own pa Franz already having bonded with her.
