Believing she is an illiterate country bumpkin, her family forces her to take her spoiled sister's place in an arranged marriage to Julian Vance, a reclusive billionaire crippled in a mysterious assassination attempt.

Behind closed doors, Vivian systematically restores Julian's mobility while neutralizing the poison that paralyzed him. Stunned by her fierce competence and secretive identities, Julian discards his cold demeanor and falls deeply for his unexpected bride. Together, the power couple orchestrates a ruthless takedown of Vivian's deceitful relatives while hunting the corporate conspirators who tried to end Julian's life.
