After being kicked out of the group's 10-year party that he helped create, music producer Zé Toledo decides to prove to everyone that he is still capable of making it big and making a comeback. The way? Create a new boy band.

Zé has already come up with the success formula for his new boy band: a singer, a songwriter, a dancer and a charismatic leader. He gathers four talented boys and makes his proposal: either they all join the group, or there is no group.

Enzo is the son of a renowned classical pianist and his entire musical background was designed to follow in his mother's footsteps. When he thinks about giving up, Paulo, Luca and Rafael convince him otherwise and make up a story for Enzo's mother to allow her participation.

Zé gathers the group and their families to make the official announcement of the formation of the band. He takes everyone by surprise when he says that from now on the four boys will live in his mansion: an artistic boarding school. Luca's younger brother Maha does not take this news well.

Happy with the idea of living in a mansion with a pool, studio and musical instruments, Luca, Paulo, Enzo and Rafael have a shock of reality after the move. Enzo and Rafael become partners in the composition. Rafael is going to do theater to overcome shyness, Paulo displays his dance skills.

Rafael tries to show his lyrics to Zé, without success. Débora complains about Rafael's presence in her play. Fátima sews the group's first clothes, in the 80's style. Felipe and Giovana unite to end the Z4. Zé decides to test Luca and Paulo's vocal skills and presents the group's first song: Teteia.

Pâmela is worried about her father's music, but rehearses with the group nonetheless. Luca's followers complain about the lack of videos on his channel and protest outside the mansion. Zé distributes functions to the members of Z4. Enzo's parents appear by surprise at Zé's house in Teteia's first performance.

Maria Lúcia and Humberto are outraged by Enzo performing at Z4. When Enzo realizes their presence, he runs away from shame. Everyone mobilizes to find him. Felipe and Giovana celebrate. Jessica and Fátima give shelter to the boy.

Enzo takes courage to assume his dreams and tell the parents the truth. Fátima makes a big change in his look. Paulo gets angry when he finds out that Enzo slept at his mother's house. Zé tries to prove to Maria Lúcia and Humberto that he is a good producer and has a great idea for that.

Rafael surprises with a text for the end of Débora's play. She starts to look at Rafael with different eyes. Giovana tells Felipe that their plan has failed. Judith puts Zé on the wall and says everything the boys try to tell him. Zé decides to search for lyrics by famous composers.

Pamela sets up a surprise party in the republic for Enzo and the Z4. Maha devises a plan to publicize the group on Luca's channel. Indira reads the coffee grounds for Judith to know if her virtual crush is a good person. Pâmela does a free rehearsal and Z4 dances the songs they like for the first time.

Pâmela moves the party to the mansion when she discovers Zé's trip to Rio de Janeiro. Without the boss around, Z4 can sing and play the songs they like. Giovana tells Felipe that Zé traveled and he sabotages Zé's plans to get new lyrics for Z4. Zé decides to anticipate his return and catches the surprise party.

Giovana brings to Felipe images of the Z4 singing at the event. He decides to keep her cell phone to leak the content on the internet. Zé is furious when he sees the video on the network and finds out about the party. Giovana makes a big scene in the workshop to say that his cell phone was stolen. Zé scolds Pâmela, Débora defends her friend. Rafael interferes and argues with Débora.
