A ten-year-old girl named Angeli has a stern, cold and seemingly unfeeling mother, Maria. To prevent her daughter from entering a forbidden room, Maria tells her daughter that a child-eating monster resides in there. Fully believing what her mother has told her, Angeli refuses to go inside the room until a prank leads her to believe that the monster keeps her friend. Going inside the room, Angeli discovers her mother’s secret.
