The documentary presents the trajectory of the singer-songwriter Mario Vivas, his passion for the Portela School of Samba, one of the most celebrated of the Brazilian Carnival. In the Theater and Cinema, he also acts as creator of original soundtracks. Great names of samba as Tia Surica and Geraldo Sorrizo, both symbols of Portela, and the veteran actress Lea Garcia, known worldwide for Marcel Camus' classic 'Black Orpheus', winner of Camera D'Or and Oscar for Foreign Language Film, help to brighten the film's cast.
