Pía is on the verge of a nervous breakdown: Her boss humiliates her, her husband ignores her, her stepson is disrespectful, and her best friend no longer listens to what she says. Pía begins having strong chest pains and, after trying many different healing methods, decides to undergo an acupuncture treatment. The Chinese doctor discovers that Pía's pain is caused by repressed feelings, and, with an ancient technique, he "removes the filter". From now on, an uninhibited Pía will realize that the only way to heal herself is to speak everything that comes to mind - which won't always bring her the best results.
