Nothing good ever happens to Pilar (a luminous performance by Natalia Oreiro). Her deadbeat husband is useless, her boss is forcing her to work with a very difficult colleague, her psychiatrist doesn’t listen to her, and people on occasion even insult her in the street. One day, Pilar’s world is turned upside down when she meets an old man who advises her to drink a mysterious potion. Waking up the following morning, Pilar feels completely reborn, and proceeds to do and say anything and everything that goes through her mind. A series of hilarious encounters ensues, where everyone will suddenly have to deal with her sudden transformation. While life appears to improve for Pilar, those around her aren’t so sure.
