A schoolteacher with a nervous disposition visits one of her students in his barn and sees something she shouldn't: a metallic box that seems to be controlling locusts. No one takes her story seriously, and even she believes she imagined the whole thing. But her story hits the newspapers, which brings David Vincent to her small Kansas town to investigate. The trouble is, the townsfolk resent strangers - none more so than the ones who are aliens in disguise. Written by J. Spurlin

Small Community Nightmare
2 October 2017 | by See all my reviews

'Nightmare' is one peculiar episode - it has some of the best and eeriest moments of the first season, and also some of the worst and most ridiculous. There is tension and action and also plot holes big enough to drive harvester through.

The invaders have worked out the plot to use flesh eating insects to wipe out human population. For that they seem to use some sort of powder or chemical mixture. The plot starts in small town in Kansas that is nearly in the heart of United States. When school teacher Ellen (Kathleen Widdoes) witnesses aliens using a machine that controls insects the story finally gets into newspapers. David Vincent arrives into town to investigate. He finds out that Ellen is little bit mentally unstable thanks to tragic event from the past. Still he believes the woman while the rest of the town, including Ellen's fiancée, are convinced that she just imagined it all. The town's folks are not very friendly towards nosy Vincent and again he has hard time to find himself allies.

Not the best episode, but the creepy small town atmosphere, the constant threat and fast paced action make it one of the most enjoyable ones. Truly nightmarish chapter. And Roy Thinnes is awesome as always.
