She Saw EverythingEpisode 4

Elena, heiress to the Moretti Group, lost her sight in an explosion orchestrated by her husband three years ago. Her biological son Luca was imprisoned, while a foster child Noah was disguised as Luca to take his place. A fall accident restored her vision, yet she chose to feign blindness. With the help of the family lawyer, investigators and technical consultants, she gathered solid evidence and rescued both children. Eventually, she staged a live broadcast during a hotel gala, forcing her husband to confess his crimes in public. She completed her perfect revenge and pushed forward the legal restructuring of the group.
