Ye Wantang, a modern embroiderer, and Liu Ruyan, the legitimate daughter of an ancient family renowned for its embroidery, exchange bodies for ninety days. Liu Ruyan squanders six years of Ye Wantang's hard-earned savings, ruins an extremely valuable order, and even injures her hand, arrogantly declaring, "It's not me who has to suffer anyway." But when Liu Ruyan returns to ancient times, she is dumbfounded to discover that the new competition rules require her to handle the needle herself. Meanwhile, Ye Wantang discovers at the Liu residence that the supposedly talented heiress cannot even do a basic running stitch, and that her famous masterpieces were all produced by exploiting ghost embroiderers. Determined to master extraordinary embroidery techniques, Ye Wantang fights for justice for exploited embroiderers. After ninety days, the arrogant heiress falls from grace, while Ye Wantang uses her own hands to embroider herself a magnificent new life.
