After a man suddenly disappears without a trace, his sister goes in search of answers. Unable to convince the local police that her brother must be the victim of foul play, she enlists the help of an unlikely private investigator who is haunted by a troubled past. When Rehnquist left Miami and the police department for the tranquil solitude of the Florida Keys, he thought that he had put the days of pursuing violent criminals behind him. That was before a beautiful, blonde stranger unexpectedly interrupted his quiet, simple life with a desperate plea for help, a personal challenge, and the opportunity to repay an old friend for saving his life years before. When he reluctantly agrees to help her, he has no idea where this case will lead him, or that discovering her brother's secret might well cost him his own life.
