A pair of twins (Lukas and Elias Schwarz, going by their real first names) suspect an impostor underneath the facial bandages of a woman that's supposed to be their mother (Wuest) after cosmetic facial surgery. The setting of a lakeside house is not only beautiful, but it also creates a sense of isolation and quietness that will keep you on the edge of your seat. The film is not without its flaws; particularly with how it handles its twists and turns—but just like some of the best lies have truth to them, some of the best twists have obvious to them. Even still, directors Fiala and Franz execute well enough to keep you engaged throughout, and do a pretty decent job of throwing you off track at random times, despite the film being guilty of trotting down the path of predictability.
