Stark heiress Mara is badly wounded and thrown into the Atlantic by her husband Jackson and best friend Debbie on their 10th anniversary yacht. Her twin sister Sarah returns as mysterious designer Veyra, impersonating Mara for revenge. Using DNA evidence, biometric keys and betting agreements, she seizes corporate control and forces Jackson into bankruptcy and divorce. The real Mara, with amnesia and plastic surgery, is manipulated by Debbie to incriminate Sarah until her memory returns. At the wedding, Jackson’s crimes are exposed. With Sarah’s help, Mara acts in legitimate self-defense and kills Jackson, and the sisters reunite.
