A new school year starts in college High School Brazil. With the resumption of classes, Olavo, the team captain of futsal-maned wolves, learns that her neighbor and classmate Renata changed much during the holidays. Paula, unchanged, still as vain and always spending his time mastering the Fellipe brother and her friends Alicia and Clara, or as she prefers to call: The Invisible. The director of the college and Professor Marcia Arts, invites students for the first Music Competition. It will be the opportunity for students to demonstrate to be true music stars. Only one band will win, one that is able to work in a team, seek to overcome and know that not only form a group with the best artists - it is essential that prove to be the best people. Working against the clock and with few resources, students strive for the big day. Olaf and Renata, together with Moroni, Bia, Samuel, Fabio and Ed participate in the tender forming a band they called The Tribe. Moroni initially mocks the possibility of singing. The other guys that are part of maned wolves do not get too excited about the proposal to form a band and sing in the Music Competition, but have come to accept the idea. Renata, who had been sidelined by Paula in her group, joins Olaf and his friends to form the band. Realize they need help from Fellipe for everyone to find the harmony to sing. At the same time, Paula tries to harm the banda so they are not successful. She does not conform to see that his brother Fellipe accepts the invitation and the Band A Tribe seeks to do everything so that he does not support the banda rival. Go so far to circumvent the rules of the contest. Upon presentation, Paula loses her voice and Karol who is holding the presentation can finally show her vocal talent. Yet she seeks Paula behind the scenes to end the show. The attitude of the people makes Paula redeem himself at the end of the Music Competition and realize that friendship and good family relationships are more important than mere vanity. In turn, the father of Olaf recognizes that the child can make their own choices and give pride both in sports and in other areas, as was the case of music.
