One day, as Luisa goes to pick up Mayumi from school, their house catches fire and they lose everything they own. With nowhere to stay, Hernan agrees to let Mario and his family stay in his house until they can find a new place.
Hernan lives with his wife Brenda and daughter Isabelle in a small house. Brenda is not happy to see her husband bring Mario’s family into their house and demands that they leave after a few days or they will have to pay rent.
Luisa is not able to sleep because of the problems she and her family are facing. Hernan consoles her when he finds her outside but when Brenda finds the two of them together, she accuses Luisa of trying to seduce her husband.
