**SPOILERS** With a much better then average cast, for a straight to Video movie, you would have expected the film "Natural Enemy" to be a lot better then it actually is but only ends up just being just another psycho with an grudge flick that has young William MaNamara as stock market whiz kid Jeremy Harper out to get even with those who abandoned and kicked him around.
After murdering a number of people including his both adopted and surrogate fathers by setting them on fire as well as having his natural dad, who's young wife Jeremy was having an affair with, murdered by hanging him on the chandlers of his home this out of control psychotic sociopath ends up getting nailed in the end by Chris, Christian Tessier; who unknown to him happens to be Jeremy's step or half-brother.
With his mother 17 and pregnant in high school she has her new born child, Jeremy, given away to an orphanage. It's there where Jeremy ends up being adopted by some three different sets of parents, one of whom he sets on fire at the beginning of the movie. Jeremy always wanted to get to meet his real mother and show her just what he thought and felt about her and after years of searching that magic day was about to come true.
Reaching adulthood the psychotic young man plans a get together with his real mom the now Sandy Robards, Lesley Ann Warren, that's to take place on his 25th birthday the following Saturday November 30th. Jeremy plans give her a Mother's Day present that she'll never ever forget even if it kills him and her.
Working like a maniac studying finance and the world of stocks and bonds Jeremy becomes a market genius graduating at the top of his class at the prestigious Harvard Business School. All this hard work is so that Jeremy can get close to him mom and her husband Ted Robards, Donald Sutherland, who's a stock broker and what better way to do that then he himself be a big wig and expert in the stock market and end up working for Ted. Getting a job with Donald's firm for half the salary that he could normally get anywhere else Jeremy want's to destroy Donald's business and his wife's Sandy's home life like he feels that Sandy destroyed his life by abandoning him as an infant.
Worming his way into the Robards home as well as his business, like a rat gnawing through a cement wall, Jeremy is now in the perfect position to do what he was planning to do for so many years: get even and get even BIG for what Sandy did to him.
I for one was shocked not only to see beautiful Tia Carrere have such a small part in the film as the missing and adopted child investigator Christina D'Amello but also get killed off so early without ever being giving a chance to show off her breathtaking natural and physical attributes to an eager audience just dying to see them.
Jeremy as sick as a man infected with rabies and on crack/cocaine plus LSD added into the mix goes out to break Ted financially by making it look like he's hiding something from the FBI and Securities and Exchange Commission investigators. That sleazy action by Jeremy has the poor and confused man blackballed out of the stock brokerage industry.
Jeremy murders both his natural father Stanley Knox ,Viasta Vrana, whom he also destroyed financially and his fathers young wife as well as Jeremy's mistress Gina ,Lenore Zann. It's then that this low-life creep also has to murder the gorgeous and unsuspecting Christina D'Amello who's body he threw down a garbage disposal shoot after having the whole sick and disgusting event secretly video taped in order to show and "impress" his natural mom Sandy.
On the eve of his birthday, November 30, Jeremy planned to have his mother Sandy murdered for all the pain and suffering, that's only inside Jeremy's sick and diseased mind, that she caused him after having already murdered her husband Ted. Jeremy made just one big mistake that brought his demented and insane plan to a complete halt and turned him into a king size pin cushion. The lowlife murdering creep decided not to murder his wimpy half-brother Chris but to torture and humiliate him instead! It was that sadistic streak in him that put Jeremy Harper away for good in a place where he can't hurt or murder anyone anymore.
