Modern weaver Su Jin travels through time, becoming Su Jin, a widowed bride of the Zhou family. Facing the clan's pressure to remarry and their covetous plots regarding her dowry and weaving skills, she makes a seven-day wager, staging a comeback from a desperate plight through her extraordinary textile artistry. Skillfully utilizing dead silkworms to spin silk and create cracked-ice patterned satin, she sees through the Shen family's manifold schemes, joins forces with the young Zhou Mingyan, and finds the jacquard loom and the heavenly granddaughter's brocade secret manual left behind by her late husband Zhou Dalang. After enduring court cross-examinations and beating the grievance drum, she exposes the truth of the Shen family poisoning two generations of Zhou family weavers. Ultimately, Su Jin establishes the Brocade Heart Workshop, opens a weaving school for women to impart weaving skills without compensation, takes in suffering women, and restores the lost heavenly granddaughter's brocade to its former glory.
