The Flying Serpent

A crazed, avaricious archaeologist uses an unusual means to protect his newly discovered Aztec treasure in this horror movie. To guard it, he invokes the Aztec plumed god Quetzlcoatl. All the digger has to do is put a feather upon the back of the victim and the enraged god, in the form of a prehistoric bird, will swoop down and claw the victim to death until it can get it's stolen feather back. Essentially a remake of The Devil Bat.
