this cheapie prc production be pretty much a re working of the same studio 1941 the devil bat and only it get george zucco and a killer bird instead of bela lugosi and his lethal monster bat . zucco be a professor who discover montezuma treasure and aim to protect it for himself by unleash the mythological half reptile quetzalcoatl ( it funny hear zucco personally address his fly feathered serpent a such ) to dispatch his enemy . unfortunately and this be nowhere near a much fun a it predecessor . still and there be some pretty neat attack scene of the soar creature flap through the air to latch onto it victim throat .
