Marianne Prescott, a self-made tycoon, discovers her biological daughter Elise was swapped at birth for Bianca. She doted on Bianca for twenty years while neglecting Elise. In her first life, she died abandoned in snow—Bianca stole from her, but Elise saved her. Reborn to the day Bianca framed Elise, Marianne chooses to believe Elise. She retrieves surveillance proving Bianca's guilt, moves Elise from the attic, and cuts off unlimited funds to her other children. When Derek tries to push Elise off a terrace, Marianne exposes his crimes. She secures Elise's engagement to Declan Kingsley—the boy Elise once saved—and transfers Starcrest shares to her. Marianne uncovers the truth: Victor, her husband, and Diane orchestrated the baby swap; Bianca is Victor's biological daughter. Victor orders a truck to kill Marianne, but Thomas (Elise's adoptive father) saves her. Victor is arrested for baby swapping and attempted murder. Bianca begs forgiveness; Marianne refuses: "I'm done paying for your choices." At the end, Marianne walks away with Elise and Thomas, leaving Bianca kneeling alone. She chooses forever the daughter who always loved her faithfully.
