Bats is a 1999 American horror film[1] directed by Louis Morneau, written by John Logan and produced by Bradley Jenkel and Louise Rosner.

Dr. Alexander McCabe is secretive about the situation, but admits that the bats were genetically modified by him to become more intelligent and also omnivorous so they would not be in danger of extinction any longer.

Aided by Sheriff Emmett Kimsey and CDC specialist Dr. Tobe Hodge, Sheila and Jimmy begin to search for the bat roost.

Emmett decides that Gallup needs to be evacuated, and the mayor is told to broadcast a warning to all residents to stay indoors and secure their houses.

The bats invade the town and, within minutes, chaos ensues and several people are killed, including Dr. Hodge, who sacrifices himself to save Sheila.

Jimmy arranges for an NGIC Industrial Coolant that uses freon, carbon dioxide, and oxygen to be dropped off as soon as the roost is located, in a cave that Emmett recognizes as an abandoned mine.

Sheila and the others use electrified fences and blowtorches to keep the creatures at bay, but it is revealed that McCabe, actually insane, has created the bats to be the ultimate predator, specifically designing them to kill humans.

One final bat survives the freezing temperatures and burrows out of the ground, only to be crushed to death by the group's car as they drive away.
