Vampire Bats2005

Horror Vault's take

When a string of gruesome deaths rocks a small community, a sharp-minded biology professor suspects the culprit is far more dangerous than anyone wants to believe. Her investigation points to a mutant strain of vampire bats with a lethal hunger — and a population that's rapidly growing. With local authorities slow to act and the attacks escalating, she must use every resource at her disposal to contain the threat before the night belongs entirely to the swarm.
