After their parents` divorce, teenage Vira and her younger brother Dino move in with their mother. At first, things seem normal - but soon, unsettling changes begin to appear. Their once-loving mother becomes unrecognisable: cold, violent, and consumed by strange rituals and supernatural markings. As the mother`s behaviour spirals into madness - laughing hysterically, whispering eerie threats, and attacking her children - the siblings are forced to confront a terrifying truth: the woman living with them may no longer be their real mother.
