A group of Delta Force soldiers, accompanied by a CIA agent, are sent to the Belzan forest in Chechnya in search of a rogue American weapons researcher, Dr. Benton Walsh. As they search for Walsh’s camp, they are attacked by genetically-altered carnivorous bats. The survivors attempt to reach helicopter extraction but encounter various challenges, including Chechen rebels.
