After his wife's death, Joseph Binder wants to sell the family farm. That surprises his kids, mainly unpopular adopted son Philipp, who fights and storms out in the Alps and joins geology-Ingeneers Carsten and Sabine Lechner, whom mountain guide Jan Fugain and rescuer Tobias Herbrechter accompany to repair broken measuring equipment. They are hit by a rocks avalanche. Philipp however acts on dark motives, vindictive to his biological mother who gave him up for adoption. Tobias is missing himself. Philipp stole explosives for his ultimate revenge, also on the Binder farm family.
