For Paris Gibson, her popular late-night radio show is both an escape and her one real contact with the outside world. But when a listener who identifies himself as "Valentino" tells her that her on-air advice to the girl he loves has caused her to leave him and that now he intends to exact his revenge. First he plans to kill the girl, whom he has abducted -- which he says he will do in 72 hours -- then he will come after Paris.
