Spain, 1936 and the brink of civil war.
Young, poor Sara Quiroga is swept up in a whirlwind romance with her wily love Ramiro. Fleeing Madrid together for Morocco, her love blinds her to 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, Sara is able to sew for the glamorous foreign English and German women in Tetouan. Privy to their unbridled gossip, Sara becomes invaluable to the British secret service, a position that is filled with untold risk.
A tale of danger, espionage, love and war, The Seamstress is a WWII tale like no other.
