[PART 1] The rescue team is puzzled when called by an old man who was covered by an earth slide down an Alp, warning there's another victim 'in the mountain' but dying before the helicopter arrives. They and the police only find a non-swimmer who abandoned an small boat in the lake down the slope. Andreas Marthaler and Tobias Herbrechter ignore that Ulli Jäger was thrown down a deep copper shaft by the slide, wounded and desperately seeking a way out. Andreas is shocked when the senior is identified as Alois Maria Kofler, Emilie's father, who left the region years ago when the mine went bust. Emilie and sister Jessika, who left for Salzburg, can only speculate why he returned.
