A missing persons case linked to the boarding school is reopened. When the friends play a strange game, tensions between Butsche and Roman boil over.

Butsche visits Elena for help with Elsie, angering Roman once again. Nadja drops a bomb on Grünberg and tests a provocative hypothesis about Katharina.

When another victim turns up, the police zero in on a suspect. Nadjas lingering doubts -- and a tip from Köhler -- lead to a shocking confrontation.
