Summary [PART 1] The rescue helicopter feels to locate Thomas Wieser, who called them, panicking about 'moving mountains' and danger to many people including his daughter Marie's class on maintain trip but falls silent, presumable unconscious. Andreas, dangling on a rope,Toni and Michael only finds his backpack on a ridge. Andreas must be hastily dropped in a tree while the helicopter near-crash-lands with damaged rotors due to a pebble hail. Marie and her class are safe, but the brat refuses to go back to her mother even temporarily, so Andreas takes her home for now, promising to find Thomas. [PART 2] While Thomas Wieser remains missing, Andreas and lover Bea Kleinert drop off Marie at her mother's work-floor, finding her unloving to the brat, but adulterous with her boss, who runs a measurement equipment firm. Andreas uses Thomas Wiesers's double keys -proof he was moving- to search his new home, finds lots of geological research material, which the team matches with the notebook to realize he was proving drilling as for major construction damages the plaster pockets in the layer below the rocks, rendering whole mountain sides unstable. That materializes uncomfortably close, and Tobias's father, the hotel magnate Peter Herbrechter, finds his new natural spa project went wrong even in criminal senses. Meanwhile Andreas's father finds a way to cash his insurance payoff and invest it to keep busy usefully.
