In the Netflix original film Sunday’s Illness (La Enfermedad Del Domingo), Anabel abandoned her daughter Chiara when the girl was barely 8 years old. Now, thirty-five years later, Anabel is a respected philanthropist when Chiara suddenly turns up with a strange request: she asks that her mother spend 10 days with her and after that she will renounce all relations and claims. Compelled to comply, Anabel is understandably uneasy but what she doesn’t know is that Chiara’s hidden agenda is far different than what she imagined and that she will have to face the most important decision of her life.
