Sienna, the biological daughter of the wealthy Crawford family, is constantly neglected and wronged by her parents, brother Michael and fiancé Cassius, who dote on adopted girl Christy (posing as Ava). The whole family pretends to lose their memories of Sienna on purpose to protect Christ, repeatedly humiliating Sienna, forcing her to donate a kidney to the adopted girl even after learning she is pregnant. During a kidnapping crisis, they abandon Sienna and choose to save Christy. Heartbroken Sienna jumps into the sea to fake her death. With the help of Troy, a mysterious businessman, she uncovers the truth that Christy is an imposter controlled by a mysterious system. Sienna takes back her family enterprise, punishes the hypocritical adopted girl, and cuts all ties with her remorseful family and ex-fiancé, starting an independent new life free from their betrayal.
