An invisible alien presence invades rural Texas, revoltingly killing its victims, reanimating their corpses, and sending them on a bloodthirsty rampage. Scientists at a local research facility set out to study the phenomenon while top military brass are hell-bent on nuking the bloodsuckers. A young photographer and his girlfriend find themselves ensnared in the bloody mayhem. Taking a comic swipe at drive-in exploitation films, this horror sci-fi farce is so true to the genre, that it joins the ranks of the movies it pokes fun at.
