Cecilia arrives in Guadalajara for the first time to study at the Faculty of Letters and become a writer. There she meets Nicolás and Aristeo, young men who claim to be the founders—although, in reality, they are the only members—of the underground ultraism, a literary movement that aims to change Mexican letters. Through them she meets Pita, an irreverent and openly bisexual poet, with whom she forms a genuine closeness. Cecilia finds in this group a new sense of belonging, until the friendship that sustains it begins to crack due to envy.
