The magnetic Elda dreams of becoming a rock star. When she's not singing on stage, she's Diego Detona, a teacher living with his family in Concordia who has doubts about his transition. Which is his true alter ego? The determined and ambitious Elda or the shy and insecure Diego? He tries to find the answer on a pilgrimage to the shrine of a trans woman who was murdered and later transformed into La Muda, a kind of folk saint to whom the townspeople turn for help.
