Miller (Hugo Stiglitz) is a reporter on to something when he sees passengers disembark from a plane and start attacking and murdering whomever they come across -- no, they are not upset with their service, they are zombies -- or more accurately ghouls who need human blood to stay alive. While flight attendants may contend that more than one ghoul is on any flight, this group was contaminated by a man exposed to radiation that leaked from a nuclear plant, and they are hereafter identifiable by their black-face make-up, if not their eating habits. When Miller tries to notify the citizens that these monsters are on the loose, he is rudely stopped by a nasty general (Mel Ferrer) who does not want to make the public unnecessarily hysterical. The monsters have a molecular structure that is not affected by bullets, and so in imitation of the accepted code that zombies only die with a shot to the head, the general launches his attack "aiming for the control center" of each zombie head, before everyone is converted into the blood-thirsty monsters. With anemic acting, murky color, and other technical problems, this is simply another zombie film among the masses.
