Their mother's face wrapped in bandages following plastic surgery, two young Austrian twins begin to question her identity, and resort to torturous tactics in a bid to discover the fate of their "real" mommy. In the aftermath of an unexplained trauma, nine-year old twins Lukas and Elias (Lukas and Elias Schwarz) spend their days playing in and around their secluded Austrian home as their increasingly short-tempered, single mother (Susamme Wuest) seeks peace and quiet while recovering from facial reconstructive surgery. Distressed at her unusual appearance and disturbed by her borderline abusive behavior, Lukas and Elias soon begin to question whether the woman under the gauze is truly their mother at all. Those fears are apparently confirmed when the siblings stumble across a photo album containing a picture of their mother with a woman who appears to be their twin, and decide to torture the suspected intruder into confessing her true identity.
