In a twenty-four-hour span, Rafael Alvarez led North Amistad High School’s Mariachi Alma de la Frontera to their eleventh consecutive first-place win in the Mariachi Extravaganza de Nacional; and met, made out with, and almost hooked up with one of the cutest guys he’s ever met. Now eight months later, Rafie’s ready for one final win. What he didn’t plan for is his family moving to San Antonio before his senior year, forcing him to leave behind his group while dealing with the loss of the most important person in his life - his beloved abuelo. Another hitch in his plan: The Selena Quintanilla-Perez Academy’s Mariachi Todos Colores already has a lead vocalist, Rey Chavez - the boy Rafie made out with - who now stands between him winning and being the great Mariachi Rafie's abuelo always believed him to be. Despite their newfound rivalry for centre stage, Rafie can’t squash his feelings for Rey. Now he must decide between the people he’s known his entire life or the one just starting to get to know the real him.
