Das Nebelhaus.

Four former classmates, Philipp, Leonie, Timo and Yasmin arrange reunion over the weekend in one of Philipp's properties. Philipp's wife and daughter are also present. The weekend ends in bloodbath however, with three people dead and the suspect in coma. Two years later Leonie's mother asks the former classmate of the alleged murderer, Doro Kagel, to reopen the case. She would never trust her daughter to do such an act, and even Doro starts having doubts that are only reinforced by the silence of the survivors.
