Directors Veronika Franz and Severin Fiala are experts at creating unsettling moods in cozy spaces that are slightly off-kilter. In Goodnight Mommy, a mother (Susanne Wuest) returns to her countryside lake house after plastic surgery with her head wrapped in bandages and obscuring her face. Her ten-year-old twins (Elias Schwarz and Lukas Schwarz) are disturbed by a shift in her post-operation behavior and begin to doubt if the woman underneath all the gauze is in fact their mother.
