Lucy Lawless (Boogeyman, EuroTrip) stars as college biology professor Maddy Rierdon, a wife and mother that recently moved to Louisiana to raise her kids in a friendly environment. It's a quiet town until one of her students is found dead, two of her other students become suspects, and Maddy's insistence that the marks on the boy's body could only have come from an animal attack falls on deaf ears with the local law enforcement. It doesn't take long before other victims emerge, and Maddy's studies indicate that the attacks could only have been administered by vampire bats, which are not only not indigenous to the area, but their behavioral patterns are inconsistent with what science already knows about them. While the police are hell-bent on poisoning the swarm of bats, Maddy thinks that the problem will still persist until someone finds out just what is making the bats attack so voraciously. With the assistance of her biology class, Maddy gets on the case. It's very clear why Vampire Bats was made, as it appeared as the CBS Movie of the Week the day before Halloween. It serves to offer up a few scares in typical teen horror movie fashion.
