The young trapeze artist Alma is part of the show of a miserable traveling circus. In an act of desperation, Alma commits incest with her father, a sick clown obsessed with the woman who abandoned them. Determined to have his child, Alma leaves the circus and joins a group of preachers led by Refugio, a woman who performs puppet shows with biblical passages in poor neighborhoods.
