With a short and intense life, Dolores Duran left her name in the pantheon of great names in Brazilian music. Living in a time when women had to follow strict moral standards, Dolores had no doubts: she spent the night in bars and parties, drank, smoked and allowed herself to be free to relate to whoever she wanted, challenging the macho structure of the 1950s. With many archival footage and testimonials from friends, family and ex-boyfriends, the film tells the story of an important and little-remembered character.

By day, Mari and her friends broadcast their spiritual devotion through pastel pinks and catchy evangelical songs about purity and perfection, and by night they form a vigilante girl gang, prowling the streets in search of sinners who have deviated from the rightful path. After an attack goes wrong, leaving Mari scarred and unemployed, her views of community, religion, and her peers begin to shift.
