[PART 1] Environmentalist siblings Tom and Jana Huber desperately seek to document a golden eagle nest to obtain site protection before their father, real estate tycoon Dietrich Huber, and his local partner Peter Herbrechter, can build a ski resort there. She falls, requiring a helicopter rescue by the Ramsau aces Andreas and Tobias, which costs the pilot his license. Tom reproaches Jana she wants to 'revenge' their late mother more then preserve the birds, blaming their father while he wants a family reconciliation. While Andreas and Jana share his mobile home bed, his father Franz Marthaler joins the conservation team as nocturnal observer, fearing egg theft, and calls Toni Stössl out of bed to investigate a suspicious climber, but before they can properly interrogate him, a slide tarns them.
