A scientistterroristgeneral loon (not really sure what he is) puts a toxin in the local water supply that turns ordinary folk into rampaging zombie-like creatures. Wings Hauser, Bo Hopkins, and Company set off to put a stop to... well, to put a stop to whatever is going on. That's really all you need to know. The rest is either unexplained or makes no sense at all anyway.
Is Nightmare at Noon good? No. Is Nightmare at Noon fun? You bet ya. Zombies, a mysteriously mute albino, explosions, Wings Hauser... what more do you need? For all its many (many, many, many, many, etc.) faults, being dull is not one of them. There's a shoot-out, chase scene, or murderous rampage around every corner. Highlights for me include: Brion James albino get-up - including white eyes, hat, and suit; George Kennedy - always a pro regardless of the material; the green acid-filled zombies; Kimberly Beck - always enjoy seeing her; and the above average amounts of sweet 80s cheese.
