Denise Morgan is the heiress of the Morgan Group. Despite her father's objection, she married below her station to a man called Thomas Rayborne. As Denise loved Thomas deeply, she was willing to endure the oppression of her mother-in-law and elder sister-in-law. Even when she learned that Thomas intended to seize the Morgan Group, she forgave him many times. On the seventh anniversary of their marriage, Thomas and Grace Morgan teamed up to have her die underwater while diving.
Victoria Anderson, Denise Morgan's twin sister, was abducted when she was a child and could not be found by the Morgan family. When Victoria found Denise, she learned that Denise had died. She suspected that there was something strange about Denise's death, so she returned to investigate the truth for her.
