Bianca Anderson has been contracted by her father to marry Angelo de Rossi, the heir to the Rossi family's multimillion-dollar company, since she was a child. But having grown into an independent woman, she finds it odd to marry a man she has never even met. She tricks her twin sister, Camilla Anderson, into taking her place just a few days before the wedding.
On the wedding day, Bianca is shocked to see a very handsome man at the end of the aisle. Desperate, she asks Camilla to call off the charade, but it's already too late. Her twin sister is already drawn to Angelo. Heartbroken, Bianca moves into the mansion with Camilla and Angelo, pretending to be uninterested in the marriage. She has only one goal in mind: to take Angelo back.
A couple of weeks later, a popular blog publishes DNA test results claiming that Camilla had a child and abandoned him as a teenager. The evidence is damning, and she is unable to defend herself. Disappointed, Angelo follows the advice of his best friend, Leo, and seeks solace in Bianca's arms. He grows closer to her, and Bianca eventually lures him into bed. Being a decent man, he sets a date for their wedding.
Not long after, Camilla discovers that it was her sister, Bianca, who was behind the plotting all along. Furious at her betrayal, she vows revenge, putting everyone on edge. How far will she go in her quest for love and vengeance?
