Madrid, late 1940s. Marta has a promising future when she meets Antonio, but a misunderstood loyalty to Rafael will turn their lives upside down. When Antonio falls ill, Marta is forced to go to work, exposing herself to Rafael's jealousy, the gossip of the neighborhood and the indignation of a humiliated husband. The appearance of a modern and wealthy businesswoman will give Marta an unexpected opportunity that will perhaps allow her to save her own survival and that of her daughter Elena, and finally find her place in the world.
