[5] In 1999, in the fictional city of Rio Vermelho, the families of vigilantes Ramirez and Matheus lived in war for generations until Maria da Paz (Juliana Paes) and Amadeu (Marcos Palmeira) fell in love and sealed a peace agreement between them.

Twenty years later, Maria becomes a successful baking entrepreneur thanks to family recipes, although she never gets along with her daughter, Josiane (Agatha Moreira), who criticizes her behavior and appearance.

Meanwhile, Maria's nieces took different paths: Vivi (Paolla Oliveira) became famous on the internet for her charisma, being everything Josiane always dreamed of, and lives an overwhelming romance with Chiclete (Sérgio Guizé) without knowing that he is a hitman sent to execute her, although he also loves her.

The main inspiration for Walcyr was the telenovela Vale Tudo, written by Gilberto Braga, Aguinaldo Silva and Leonor Bassères in 1988, from where he used the story of the bad-natured daughter who steals from her own mother to try to rise socially in Rio de Janeiro.

[64] In November 2018, Walcyr Carrasco and Amora Mautner traveled to the interior of Espírito Santo to choose where filming would take place, but the leadership gave up using the state without explanation.

Laura Cardoso was announced in the cast in December 2018 and even gave interviews giving details about the character, however, she was replaced by Betty Faria shortly before filming began, since the management feared that the actress's health instability would hamper the progress of the plot.
