Plot Synopsis

A former USDA voracious insect specialist, who is now a college professor, finds life more complicated when one of her students is found dead with his body covered in mysterious puncture marks and completely depleted of blood. When two of her students are implicated in the boy's death, she gets caught up in the investigation and discovers that he was killed by a swarm of bats. When other attacks occur and more people are found dead, evidence leads her to discover that these are not ordinary bats, but aggressive vampire bats that have mutated due to a tainted water supply. She must race against time to find a way to stop their deadly progress.
