Shen Wudu wields the Soul-Summoning Lamp and establishes a cruel bargain: unjustly killed souls offer up their spirits, and she reverses life and death, returning to the moment they were murdered and coming back for revenge in the dead person's skin! The true legitimate daughter is cruelly burned alive in a fire set by her adoptive sister; a decorated general's wife is framed by the person beside her pillow, leading to her entire family being sentenced to execution; and a nation's empress, wrongfully accused, drinks poisoned wine in the Cold Palace. Three souls who died bearing grudges cross the boundary between yin and yang, demanding that she settle their blood debts. Three seemingly unrelated bloody cases are tightly intertwined. She believes herself to be the player moving the pieces, unaware that from the very beginning, she has fallen into someone else's meticulously laid web?
