During the military dictatorship in Brazil, Lorena, Lia and Ana Clara, three university students of different social backgrounds and origins meet at a nun's pension in São Paulo. Besides their differences, they become close friends, sharing their dramas and dreams, helping each other until the day they have to separate permanently.

The documentary is a tribute to Theater based on the trajectory of Clarice Niskier who made her job her own lifestyle. As a central axis, interviews with the three directors with whom Clarice developed long partnerships: Domingos Oliveira, Eduardo Wotzik and Amir Haddad. Through an intimate and sensitive look, the film reveals her passion for the craft, her life experience, her poetic worldview, her spiritual and intellectual search, pains, joys, losses and gains. Clarice makes the black box the more than perfect symbol of her own Universe: the Theater.
