Embroiderer Shen Zhiwei is accused of deliberately sewing the celebration's phoenix pattern incorrectly. Discovering abnormalities from the new knot of the red cord cover and the seam opening of the flying ribbon, she insists on meeting the empress with the original items.

She must not only prove herself blameless, but also strive to give the next small person a chance to finish speaking.
