After discovering her fiancé Julian’s infidelity, Taliesin seeks revenge with a one-night stand at a bar — only to find out the stranger is Julian’s estranged half-brother, Isaen, who has returned after fifteen years to investigate their father’s mysterious death. Taliesin hides her identity as world-renowned designer “Vivian,” determined to reclaim her late mother’s company and legacy from her greedy father, Dorian.
Isaen recognizes Taliesin as the girl he once loved and aggressively reenters her life, offering ruthless protection. As Vivian, Taliesin secures 40% control of her mother’s company. Julian’s mother, Blair, conspires with assassin leader Andre to eliminate Isaen and secure the Wentworth inheritance for her son.
When Julian attempts to drug and assault Taliesin, she and Isaen turn the tables. Disgraced, Julian loses his claim to the Wentworth family. A desperate Blair orders a hit on Isaen at an antique auction, but Isaen captures Andre, who confesses that Blair hired him to murder both Isaen’s father and Taliesin’s mother.
Exposed, Blair is expelled and Julian arrested for two murders. Taliesin reveals herself as Vivian, and with Isaen’s secretly acquired shares, forces her father out of the company she restores. Three months later, they marry on the Wentworth private island, leaving revenge behind for a hard-won happy ending.
