In a war-torn countryside in the 1940s, Liu Niannian marries into the Wei family to repay a debt of gratitude, only to become trapped in an endless mire. With a cowardly husband and a sharp-tongued mother-in-law, she relies on her keen perception, her golden finger, to fight for survival in desperate circumstances. The pain of losing her child, the mystery surrounding her husband's death, and the harassment of her former husband: she carefully plots every step and transforms into a stronger woman, only to discover that each act of resistance has left an indelible scar on her daughter Ding Yun's heart. This is a sorrowful song of survival, written in blood and tears by women swept up in the tide of their times, and a difficult journey toward forgiveness, reconciliation, and self-redemption.
