Day of the Dead, the third and concluding chapter in George Romero's zombie trilogy is the most distinctly 1950s-style science fiction version of the lot. Set in Florida, as the film begins the dead have taken over the world, outnumbering humans 400,000 to one.
The handful of surviving humans have taken refuge in an underground missile silo and argue and yell at each other like players in a Rod Serling Twilight Zone episode.
Among the survivors are Sarah (Lori Cardille) -- a scientist who is trying to reverse the process whereby the dead turn into flesh-eating, irrational zombies -- and Dr. Logan (Richard Liberty) -- an out-of-his-mind psychologist who wants to capture the zombies and turn them into domestic help.
Things heat up when the military tries to take over the scientific experiments.
