Rosa is a single mother who works cleaning at the Valladares home and in a chemical warehouse. She has OCD. Her son, Felipe, suffers from congenital heart disease that is curable with a surgery in the United States. Rodrigo, the youngest member of the Valladares family, rapes a young woman together with his cousin Francisco and they film it. Their friend Sebastian doesn't agree with the situation, when leaving the place he suspiciously meets with Chaparro. Rosa has to work at a reception at Sonia Valladares' modeling agency where Fanny, one of the models, is murdered. Rosa unwittingly discovers the crime scene and being threatened she begs for her life and offers to clean up the crime scene in return.

As Rosa did a good job cleaning, Chaparro spares her life, and gives her a cell phone so that he can contact her whenever he wants.

Teresa overdoses on sleeping pills and becomes critically ill, in the time Correa returns to Viridiana's school to see if he can find her trail.

The murderers dispose of the body of Fanny, the model they murdered at Sonia's event, but her cellphone isn't. Sebastián, Rodrigo and Francisco's friend, disappears and the family believes that he has been kidnapped. That night, Felipe is admitted to the emergency room.

Genoveva goes to Correa to inform him that her husband is lying: a ransom was never demanded for her son, soon Correa receives a warning from his boss and is removed from the case. Felipe recovers, but surgery is urgent. Correa and Gutiérrez go to Norberto's ranch and they find the place immaculate. María goes to a club at the request of Sonia, and a woman leads her to a private room.
