Audrey Leighton, the lark fairy from the Heavenly Palace, was banished to the mortal world for causing trouble with her sharp tongue, and accidentally transmigrated into the body of the real heiress of the Leighton family. Raina Leighton, the fake heiress of the Leighton family, is actually the illegitimate daughter of Aaron Young, a live-in son-in-law. In their past life, the two colluded to plot and murder the entire Leighton family. Carrying the resentment from her past life, Audrey is determined to reverse the tragedy and get justice from her enemies. By accident, Susan Leighton and Jason Leighton from the Leighton family can hear Audrey's inner thoughts. The two gradually see through the hypocritical faces and evil intentions of Raina and Aaron. Susan takes the opportunity to lay out plans, cooperate with Audrey to fight back step by step, making the ambitious father and daughter run into obstacles one after another, suffer the consequences of their own actions repeatedly, and continuously suffer double blows to their careers and reputations.
