A giant extra-terrestrial bird with an anti-matter protective shield is terrorising the world so a military pilot (Jeff Morrow) and his scientific girlfriend (Mara Corday) have to come up with a way of killing it. This is not the best creature feature from thr 1950's, but neither is it the worst. However the monster is one of the worst attempts at creating a flying monster in film. The science and the script are poor, leaving little for Jeff Morrow and Mara Corday to work with. Watch forfun and not for serious sci-fi.
