Mission: Close a 16-year-old cold case: three teenage girls slain in a small Midwest town. Client: Dana Hall, twin sister of one of the victims. Troubled, amnesiac, alienated from family, suffering from horrific nightmares about the killer's identity. Investigator: William "Spence" Spencer. Thirty-six. Bachelor. Top-notch skills, on the job 24/7. Shows exceptional sensitivity to client's needs. Comments: Significant danger. Escalating threats against Dana's presence in town. Spence believes Dana is hiding something relevant to investigation. Possibility he may be hiding something himself. Has his strong, naturally protective nature compromised his professionalism? There's always a first time.
