Ana (Eva Longoria) drafts the Las Leyes cast to help out at an event for her charity, Raise Your Roof, which builds homes for families. At the event, Ana and Xavi (Jencarlos Canela) clash with their married rivals, Kate and Diego, stars of the medical telenovela Cientificos Sexy, who show up with the rest of their cast. Each of the Las Leyes cast members has a Cientificos Sexy counterpart, including Gael (Jose Moreno Brooks), whose gym admirer Julio turns out to be a new addition to the cast. Julio and Gael negotiate the struggles of being star-crossed lovers doomed by rival programming.
When Kate and Diego build a kitchen in the same time it takes Ana's team to erect a single wall, Ana and Xavi begin to doubt their potential as a team. But then Diego hits on Ana, and she realizes the picture-perfect couple isn't as solid as they seem. Ana tells Kate the truth, but it turns out Kate knows Diego isn't faithful - their entire marriage is a publicity ploy! When a fight breaks out between them, Xavi takes a paint bullet for Ana, saving her all-white outfit. Maybe they're not such a bad team after all... Meanwhile, both casts accept Gael's and Julio's relationship, which kills the "forbidden love" appeal. Not to mention their diets are totally incompatible.
