In USE YOUR VOICE, we will follow all the events after the school suffered a blackout on the last day of school, just when the long-awaited final auditions of the Musical Nucleus would take place. The students suspect that the saboteur is among them, and so they begin an investigation with the help of Cabin do Futuro. Bia, Giulia and Laura revisit past confidences and understand why they broke off their friendship. Now, armed with knowledge and more wisdom, the students are ready to unleash their voices in a historic performance.
