▪ What the series is about: The series “tells the story of the headstrong and determined Olivia Winfield, who is working alongside her beloved father, Mr. Winfield, when she finds herself unexpectedly wooed by one of the nation’s most eligible bachelors, Malcolm Foxworth. After a whirlwind romance, Olivia finds herself as the mistress of the imposing Foxworth Hall, where she soon discovers that the fairytale life she expected has quickly become a nightmare. Under Malcolm’s debonair exterior lies a dark heart, and a twisted evil lurks inside Foxworth Hall that will threaten Olivia’s happiness and that of her children.
