It is an adaptation of the same-titled 2009 novel by María Dueñas, published in the English language under the titles The Time in Between and The Seamstress.
Sira remains unemployed until Ignacio finally convinces her to apply for a civil service post, but to do this she must learn to use a typewriter.
She wakes up handcuffed in a hospital in Tetuoan (at that time the capital of the Spanish Protectorate of Morocco), alone, pregnant and with a series of debts that will later take their toll on her.
As England, Germany, and the other great powers become embroiled in the dire conflict of World War II, Sira is persuaded to return to Madrid, where she takes on a new identity to embark upon the most dangerous undertaking of her career.
Thanks to her workshop, Sira meets important people like Juan Luis Beigbeder, the High Commissioner of the Protectorate; Beigbeder's mistress Rosalinda Fox, who becomes a close friend to Sira; Ramón Serrano Suñer, Francisco Franco's brother-in-law; and Alan Hillgarth, head of the British intelligence service in Spain.
As the couturier of choice for an eager clientele of Nazi officers' wives, Sira becomes embroiled in a twilight world of espionage and political conspiracy rife with love, intrigue, and betrayal.
[citation needed] The "Theme of Sira" from the soundtrack was used by Spanish gymnast Carolina Rodríguez in her ribbon routine since 2014, including the 2016 Summer Olympics.
