On March 1, 1982, the city of Niterói enters history and hosts one of the most important cultural movements: a so-called Rock 80 Generation. Radio Fluminense FM, known as “A Maldita”, goes on the air, mixing irreverence, daring and creativity with its programming aimed at music that lacks commercial space. The boldness of believing in the new made “Maldita” become one of the main alternative communication vehicles, launching Brazilian rock groups and independent music and creating a legion of fans.

The documentary features 15 interviewees, including musicians Marcelo Yuka and Otto, actor and comedian Gregório Duvivier, artist Eduardo Marinho, writer and cartoonist Lourenço Mutarelli, psychologist and hypnologist Gilda Moura, and psychoanalyst Pedro de Santi.
