In a family marked by grief, Clarice is the "Third Clef": the granddaughter trying to follow in the musical footsteps of her late grandmother, Lola. But her dream collides with the resistance of her mother, Verônica, who, consumed by deep depression, sees music as the root of the family's ruin. On the eve of a decisive contest, the tension between the daughter's desire for a future and the mother's pain from the past reaches a breaking point, forcing them to decide whether to live in silence or find a new harmony.
