From chicken eggs, a deranged geneticist (Diane Ladd, Rambling Rose, Wild At Heart) brings dinosaurs back to life. A brilliant discovery till she turns the carnivores loose on a quiet town. They breed like rats. They prey like the plague. It's man against the most vicious beasts of all time - and neither will survive while the other is alive.
A crew of technicians is sent into a top-secret mining facility to investigate a mysterious power shortage. There, deep inside the cavernous tunnels, they discover a horrifying evolution that has occurred in complete defiance of Mother Nature...dinosaurs have returned from extinction to wreak vengeance upon mankind. Now, man and beast clash in a battle to the end. But the survival of the fittest depends upon who can escape from the mine before it explodes in a nuclear meltdown!
