Cecilia arrives in Guadalajara for the first time to study at the Faculty of Literature and become a writer. There she meets Nicolás and Aristeo, young men who claim to be the founders—though in reality the only members—of the Underground Ultraism, a literary movement that aims to change Mexican literature. Through them, she meets Pita, an irreverent and openly bisexual poet with whom she forms a genuine bond. Cecilia finds a new sense of belonging in this group, until the friendship holding it together begins to fracture under the weight of envy.
