Lu uncovers a secret while helping Cayetana with her fundraiser party. Omar worries about Samuel's fate. Ander's behavior confuses Guzmán.
Cayetana asks Lu for help with a charity event since she doesn't have many contacts in Madrid. Lu gladly accepts because she loves planning events. The event is supposed to be a small dinner with a few rich parents from the town as donors.
The event becomes huge because Lu has so many contacts. They have to upgrade the event venue and everything to accommodate all of the attendees. Cayetana rushes to Polo because their plan got out of hand: the event was supposed to be a smaller dinner of donors who would think they were giving money to charity, but really the money will go directly to Cayetana, to get her life in order after her mom was fired from all of her cleaning jobs. Polo tells Cayetana to just go with it, even as the event gets much bigger than anticipated.
Guzmán tells Lu his parents don't know about their breakup and he asks her to cover for him. She agrees as long as he shows up as her date, which he agrees to.
Lu wants to surprise Cayetana by bringing her mom to the event, so she convinces an admin person at the school to give her Cayetana's mom's number. Cayetana's mom's phone audibly rings in the next room as she is cleaning, but she does not pick up. Lu becomes suspicious.
Guzmán and Nadia discuss their relationship and they have sex in the locker room at school. Valerio sees them and video tapes it so he can send it to Lu to prove to her that Guzmán has moved on, implying that she should move on from him.
The "charity" event is a wild success – a ton of parents attend and they raise a lot of money (albeit not for charity, but secretly for Cayetana). During the event, Lu receives a phone call from a number she doesn't recognize. The woman says she is a cleaner and asks if this is why Lu called. Lu realizes it's Cayetana's mother and she gets furious because she has been tricked. Carla tells Lu not to make a scene and to address it tomorrow; Lu agrees in the moment.
Later on, everyone asks Lu to make a speech to the charity guests. During the speech, she tells everyone what Cayetana did and who she really is. She also tells everyone that she and Guzmán are broken up, that he cheated on her with Nadia, and that Carla is having sex with Samuel. She rushes off upset as the party is ruined, and she goes home to get into bed with Valerio.
Cayetana is devastated and mortified, and runs off. Lu uploads the video of Guzmán and Nadia having sex to get revenge. She tells Nadia what she did and tells her that she posted it to the internet while Ander is approached by Guzmán directly and asked if Polo killed Marina. Unable to tell him the truth, he grits his teeth and tells him Polo didn’t do it, staring him right in the eye and lying. Guzmán's mind is put at ease as Ander feels even more helpless and depressed.
The episode ends with Samuel riding home on his bike through the woods at night, while being chased by a car in hot pursuit.
