The thrills is really good and some of it is surprising. The movie is filmed very good. The music is good. The film is quite interesting and the movie really keeps you going until the end. This is a very good and thrilling film. If you like Raquel Welch, Alley Mills, Kerri Green, Natasha Gregson Wagner, Joan Van Ark, Lewis Arquette, Tom Ashworth, the rest of the cast in the film, Thrillers, Mystery, Horror, Dramas, and interesting films then I strongly recommend you to see this film today!

First things first: if you plan to watch this 1993 telefilm, suspend your disbelief immediately. Now, onto the film. An all-American clean-cut kid murders his adoptive parents and commits suicide. A gorgeous crack reporter (Welch) is on the case, writing a book about kids who kills their parents and digging into the dirt of this baffling case. After two brief "moral issue" scenes (one questioning, for half a second, the role of the media in perpetuating violence, the other questioning the role of genetics in shaping future society), her investigations lead her to a shocking discovery: not only was the kid's murder of his parents caused by a genetic deficiency, but he also had a twin sister and she, of course, could blow at any time and murder her adoptive parents. Looking quite lovely throughout, Welch is on the case, cool and glam as she hunts down this genetically pre-disposed murderous teen.Cut to Suburban USA, where two adopted teen girls live across the road from each other. One has the sane Alley Mills from "The Wonder Years" as her mother; the other suffers the far more fascinating Joan Van Ark from "Knots Landing" (expanding admirably on her histrionics from telefilm "Always Remember I Love You" a few years earlier, where she also played the highly-strung adoptive mother of a troubled teen). This film is quite implausible and unbelievable, but it is diverting enough if you have nothing better to do - and it is watchable for Van Ark's scenery-chewing performance alone (although the rest of the cast do their share of scenery-chewing too!)

I first watched this film when I rented it from a local video shop at the tender age of 14 for a sleep over party.When I was 14 the film made no sense and I was left confused at the end although I enjoyed the suspense and story line. I was left thinking about the end for days.9 years on and after years of searching for the film to buy I finally have my own copy. I have watched it again and again and again and never tire of the film. Although I am still completely confused at the ending - you really are left wondering, there are so many possibilities of what really happened! I would recommend this film for a Sunday afternoon when you have nothing to do - I can guarantee you will be thinking about the ending for days. The story itself is interesting and the acting is really quite good - whilst its not a film that is going to win any awards, it certainly kept me interested for an hour or so and was very entertaining.

After a bizarre murder/suicide, a lady reporter begins an investigation into the causes. Along the way, she discovers the murderer had a twin sister who was adopted as a baby. Worried that the adopted child had also grown into a killer , the reporter has to choose between the daughters of 2 separate families as to who the sibling is. Tense and exciting right to the end, and still I was left wondering....
