Bats

Something is approaching nights. The darkness resonating beat of wings, and strange sounds. They are the bats. Not you ordinary - it's the night itself spreading its wings and terrifying. When it comes to life the darkness, not escape her. When mutated bats attack a sleepy texas town of Gallup and destroying everything in their path, before doom can residents save only zoologist Sheila Casper (Dina Meyer - Saw 1 [2004], 2 [2005], 3 [2006], 4 [2007], Piranha 3D [2010]), which studies the behavior of bats, her assistant Them and the local sheriff Emmett Kimsley (Lou Diamond Phillips - Supernova [2000], freak show [2009]). The trio finds out that the aggressive bats are the product of a scientist who is infected with a virus, changing harmless animals into killers. The trail leads to an abandoned mine where bats are spending the night and the expedition into these gloomy places brings a chill in the back. Sheila and Kimsey must muster all the courage to be launched between the sleeping monsters and wiped out their whole colony.
