Seemingly evil from birth, Sadie Morton-Brown's increasingly sexy and seductive looks only help to give her the power she desires over others; both male and female.
Lacking any scruples or morals, she uses and abuses everyone within her reach, including her devoted parents, whose lives she leaves in ruins. She disposes of anyone who gets in her way, and, between boyfriends, utilises Sunita, the girl she seduced during her schooldays.
Escaping to America, Sadie continues her quest to fulfil her own life regardless of the harm she does to others. With no conscience at all she seduces and destroys Ricky and his family; even selling her own baby.
Leaving the USA for Spain and Danny Foster, golden boy of British football, married to a well-known model, Sadie continues, with the apparent help of new-found friend Alice, to perpetrate her immoral ways - but this time she becomes ensnared by the dark evil of her life twisting back on her.
Having spent four years locked up following a crime she didn't do, Sadie Morton-Brown once again uses her seductive charm to convince the authorities, male and female, that she is no longer a danger to society.
She is anxious to return to her daughter Danielle, who lives with Sadie's parents together with her nanny Alice, the woman Sadie knows is responsible for killing Danielle's father, her only true love.
There is revenge to be had on Alice, and the incredible secret carried between herself and her mother is finally unleashed. But her disgust at the family's friendship with Nathan, the man she had left for dead, turns to unexpected love and marriage.
Although Sadie appears normal, her jealous character is unable to lose those dark, malevolent murderous thoughts and actions; she still disposes of those she dislikes, and the evil devastation she left behind in the USA, long before her incarceration, lurks in the background throughout everything, waiting to pounce.
