He goes to study in America, leaving six-year-old Liur in the care of her grandparents, promising to return with a special doll for her. But, instead of studying, her father travels to the Andes, where he meets a mysterious ventriloquist who takes him as a pupil. Five years later, he returns home, bringing with him one of the ventriloquist's dolls. But, it is not a present for Liur, instead, it becomes a menacing presence in the house, causing strife within the family. After observing her father performing strange rituals with the doll, Liur must find a way to defeat her demons — real or imagined.
