Kingdom of the Spiders

Arizona farmer Walter Colby and his wife, Birch, have a problem on their hands: One of their cows was just killed by a creature, but they have no idea what the beast could have been. So they consult local vet Dr. Robert Hansen, who becomes puzzled and calls in scientist Diane Ashley . Eventually, the duo discovers that oversize spiders are invading the small town, putting the entire population in danger as a county fair begins.
