Chosen Survivors

A group of diverse individuals are suddenly taken from their homes and flown via helicopter to a futuristic bomb shelter in the desert, nearly two miles below the surface of the Earth. There they learn that a nuclear holocaust is taking place and that they've been "chosen" by computer to survive in the shelter in order to continue the human race. They soon face a threat nobody could have predicted: a colony of thousands of bloodthirsty vampire bats finds a way into the shelter and launches a series of vicious attacks on the group.
