A couple(Janet and Richard) go camping out in the woods near a giant swamp. After camping and enjoying nature, the couple takes shelter in what they think is an abandoned farm house. Soon, a pair of escaped convicts show up and, after much delaying of the inevitable, they proceed to rape Janet and lock Richard in a birdcage.
This LAST HOUSE ON THE LEFT-like film has to be one of the most underrated horror films ever made. It's one of the more sick and twisted early 70s shockers. Moreover, I found this to be quite enchanting and beautiful in it's perverse tone. I love CAGED TERROR. The music definitely helps lend a sense of personality to the film as well as a lot of beauty. I found the film to be quite creepy.
The flaws mainly have to do with the pacing of the film, which is to say that the film is rather slow and meandering. While I didn't mind the pacing due to the beauty and suspense of the film in question, I do think that it will both most people. The acting isn't too good nor is the dialogue, at least in the early scenes. This film takes a little more patience than usual, and it's really not for everyone.
In short, this was a good film. Not the greatest horror film I've ever seen, but it is certainly a lot of fun. It's not exactly the easiest film to find. It's possible to find it in the USED section of a lot of stores if you look hard enough. It's not for everyone, but if you're a fan of trash cinema then it's definitely worth checking out.

For starters and for the record, the term "Necromancy" describes the black magic art of bringing the dead back to life and it does NOT, in any way, relate to having sex with cadavers. That is called necrophilia and, yes, I know it's an obvious difference but I'm already getting a lot of remarks from acquaintances and relatives that I sport a perverted taste in movies! This movie is quite the opposite of perverted or sleazy, in fact, and merely just qualifies as boring, inept and terribly bad. "Necromancy" makes at least one top five ranking, namely in the list of most incoherent movies ever made! Now, director Bert I. Gordon is not exactly famous for delivering masterpieces (on his repertoire there are titles like "Earth vs. the Spider", "King Dinosaur" and "Food of the Gods") but he really surpassed himself here with a totally senseless, redundant and utterly nonsensical tale about witchcraft and secretive little towns. Shortly after the tragic experience of seeing their baby being born dead, Lori and her husband Frank move to the quiet little town of Lillith, where Frank suddenly got offered a prominent job in a toy factory. Lori is suspicious and senses an atmosphere of morbidity, especially with the town's patriarch and "owner" Mr. Cato behaving very obtrusive and mysterious. That's another thing. How can anybody "own" a town and everybody in it? Either way, Lori gradually discovers that everybody in Lillith is a witch and Mr. Cato exclusively lured her to the town because of her supernatural ability to resurrect the dead. Since many years already, Cato has been trying to bring his deceased son back to life and he's prepared to make any human sacrifice it takes. I honestly don't see the point of the whole movie. It's a blatant rip-off of "Rosemary's Baby"  one of the alternate titles even is "Rosemary's Disciples"  but the script is muddled and imbecilic beyond belief. Why isn't anyone allowed to have children for as long as Cato's son remains dead? That's just really selfish! When, where and how did Lori suddenly learn to resurrect the dead? "Necromancy" definitely contains a few genuinely uncanny and atmospheric moments, but these are unwarily accomplished either by complete coincidence or through a total lack of budget. The grainy photography provides the film with an eerie ambiance and the set pieces look cheap enough to be creepy. Orson Welles' performance  undoubtedly the low point of his career  is pitiable, and still it's the best aspect about the entire movie.
