Dead in 3 Days

A group of high school friends sit in the Austrian Alps, comfortable and bored, until each of their phones gets the same text: you will all be dead in three days. Nina (Sabrina Reiter) and the others laugh it off as a prank, then the first body turns up in the countryside around them. Andreas Prochaska keeps the police a step behind, which leaves Nina combing through what the friends did together, certain the answer is already in her own past.
