Miúcha is a singer that breaks free, in this documentary, from the descriptions that reduce her to being the sister of Chico Buarque, wife of João Gilberto and collaborator of Vinicius de Moraes or Tom Jobim. Her contributions to the bossa nova movement are deepened and we follow how she navigated her marriage and tried to define her career. The film relies on personal archives that include photographs, letters, watercolors and audio recordings.
