With Los Angeles in flaming ruins from a nuclear attack, solders mop up what is left of the deadly spider with a giant spider killing robot: Mecha-Destructor. Unfortunately, a terrorist escaped from the weapons base with a suit case full of the creatures. Shot down behind the Beluxor Hotel, the spiders make their way in the pyramid and up and down the strip devouring gamblers, show girls and destroying many landmarks.
A series of "vampire" style murders on campus has Sarah scared of her own shadow - It doesn't help that her new dorm mate Lilith wears only gothic clothing, is afraid of crosses, avoids daylight and resembles a member of the undead. Sarah becomes convinced that Lilith has something to do with the horrendous murders. When Sarah can't convince others of her outlandish theory...she becomes the next target.
