Alicia (Manuela Vellés) has returned to the family home which she fled as a child. Along with her husband, Mikel (Alain Hernández) and her nine-year-old daughter, Nora (Claudia Placer), Alicia seeks to rebuild her life while being forced to confront a past she believed forgotten and a body that refuses to die: that of Victoria (Emma Suárez), the possessive family matriarch who has fallen into a deep coma and barely survives on life support.
