The week of preparation for the concert by Calle, Juliana Velasquez, and Las Villa has arrived, but there is a problem: Calle gets sick before her rehearsal and the doctor orders her to rest her voice. Mariana prepares for her recital and invites all her friends to see her for the first time. The Villas have a strong confrontation with Mariana and debate whether Juancho will go to the recital or his photoshoot.
