Five-0 investigate the murder of Brooke Waiakea, a hula dancer, later discovering that the dance studio is a front for an escort agency. The victim reminds Dr. Shaw (Amanda Setton), Max's intern, of a past case. The team turn to the aid of Harry Brown (William Forsythe), a former HPD detective-turned-private investigator, who was helping Brooke take down the escort agency. Attention falls on one of Brooke's clients, David Waring, but he is found dead too. It is later revealed that Brooke witnessed Waring's murder, committed by Robert Young (Doug Savant), the father of Waring's wife, and met a similar fate when she was spotted.
