The Verde Valley is a valley in central Arizona in the United States. The Verde River runs through it. The Verde River is one of Arizona's last free-flowing river systems.
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 (Theraphosa stirmi). 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.
