Spain, 1936 and the brink of civil war. Young, poor Sira Quiroga is swept up in a whirlwind romance with her wily love Ramiro. Fleeing Madrid together for Morocco, her love blinds her to his real failings. Soon abandoned, left penniless and in debt to the authorities, she has to rely on the one skill she still possesses: sewing. Taken under the wing of the bullish but caring housekeeper Candelaria, Sira is able to sew for the glamorous foreign English and German women in Tetouan. Privy to their unbridled gossip, Sira becomes invaluable to the British secret service, a position that is filled with untold risk. A story of danger, espionage, romance and war, "The Seamstress" is a WWII tale like no other.
