Liana Roslyn works as a nurse at New York City Hospital. She appears to be a strong, independent and beautiful young woman who's passionate about her job. But there's so much more to her story. 15 years ago her whole life turned upside down when her parents were ruthlessly murdered by the Italian Altomare mafia family, leaving her and her brother orphans. She would have never thought that they would try to take her brother away from her as well. That day she swears to avenge her family and take down the kings of the New York underworld, the Altomare family. But revenge always comes with a price and she finds herself tangled in the middle of the dangerous liaisons of the mafia world, while she struggles to face the only obstacle she never expected: the heir to the Altomare empire, Alessandro Altomare. She was determined to start a fight with this family for her own, but eventually she has to realize that the only person she has to face and stand up against in order to achieve what she really wants is herself. Will she be able to keep her promise and take her revenge or she will surrender to passion and the dangerous affection? 'I made a promise that night. I will take them down slowly, one by one. Adagio. Just like my father taught me.'
