A shocking upheaval in the imperial mausoleum. A jade talisman shatters two women's lives.
An evil spell causes their souls to awaken in each other's bodies.
From then on, the hand that wielded a blade must hold a silver needle, and the hand that held a silver needle must be stained with blood.
At court, powerful ministers cook up schemes to seize the realm; in the martial world, old enemies sharpen their blades. Trapped in each other's destinies, the women are determined to fight their way to survival, even in the face of certain death.
A compassionate heart is their blade, and a chivalrous spirit their shield.
The stakes in this game are the lives of all under heaven, and the wager is the lives of two women.
