A year after the tragic death of her brother, 19-year-old Lisi from Kitzbühel, Austria enters the decadent world of a Munich clique that comes to the luxury ski resort of Kitzbühel to celebrate every season. But Lisi soon kicks off an avalanche that reveals the truth behind the facade full of glamor, money and hedonism – with uncontrollable consequences.

Before Lisi’s brother Joseph died, he spoke of a mysterious girlfriend who loved Mozartkugel chocolates and came from a very different world. On New Year’s Eve last year, Joseph headed up the steep, winding mountain roads to meet up with this secret lover, despite the fact that he’d been drinking and the road conditions were perilous, because she’d texted and asked to see him. It didn’t take long for Lisi to realize the secret girlfriend was Vanessa and for Lisi to blame the influencer for his death.

Now with the help of Hans, Lisi plans to make Vanessa pay for her loss and untangle the dark circumstances behind Joseph’s death. But the glamor and wealth of Vanessa’s world may prove too seductive for Lisi to uncover the truth and her investigation may have life-altering consequences for the many whose lives are entwined in this deceptively idyllic town.
