To help out a friend, and to enjoy a glamorous and fast-paced life for awhile, a guy assumes the identity of his busy and mysterious friend...and ends up being pursued by murderous drug dealers.

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.
