Karen (Maren Eggert) and Markus (Andreas Döhler) live with their children in Karen’s parents’ house. Karen’s sister Jule (Britta Hammelstein) travels with her family to Markus’ birthday party. While Karen takes everyone’s breath away with her domineering manner, Jule is the complete opposite. Gradually a front forms against Karen until everything escalates into a fiery inferno. An inferno that destroys the old to create the new.
