This is a truly wretched work.
A girl who might be a truly hot babe and has a thing for UFO's drags her two boy-toys to a secret government lab where she gets her glasses knocked off by a mutant spider and becomes a truly hot babe after which she waists no time getting the spider to off her two boy-toys then she does a wet t-shirt dance and wins the heart of a hunka hunka burning MIB(Man In Black).
Then, on their honeymoon, the hot babe and the MIB steal a secret government black heliocopter and blow up the giant spider that brought them together.
Its every great sci-fi movie you've ever seen and less. If I ever have to see this thing again I will pluck out my eyes and use them as earplugs.
