Never guessing that their very lives might be in danger, well-to-do women come from all over the country to stay at guest ranches around Reno to establish the six weeks' residency required for a quickie Nevada divorce in 1955. When a Circle E Ranch guest dies after her Cadillac plunges off Mount Rose Highway, a mountain road between Lake Tahoe and Reno, Washoe County Deputy Sheriff Ben Cameron is assigned to investigate the accident. His inquiries lead him to question everyone at the Circle E, where he meets Mary, an attractive prospective divorcée from New York. Unfortunately, Mary soon has an accident of her own. In the meantime, Ben's case takes a turn as twisty as the Mount Rose Highway, and when Mary suffers a second accident, he figures that someone is out to get her. Unless Ben can discover who's targeting the out-of-towners, some of them won't live long enough to have their day in court.
