Vivian, a veterinarian deep in debt, marries into a wealthy family to save her mother, only to discover that her husband, Liam, has a split personality—by day, he is as violent as a demon, but by night, “Luke” is as gentle as a lover in the early stages of romance. Caught between conspiracy and a twisted romance, she must battle her uncle, who covets the family fortune, and seek revenge against the family that abandoned her. Ultimately, she helps Liam dispel the darkness within him, merging his two personalities, and secures a path to survival for her child and her mother.
