A strange spider from the depths of a jungle is accidentally transported back to the good old USA. Through numerous coincidences and accidents, it finds a home in the barn of a doctor's new home. After it mates with a local spider, thousands of little spiders run riot in the small town. This wouldn't be too much of a problem, except that these "aren't ordinary spiders"; they're killers. The local pest exterminator has a go, but... So it's up to the Doc to save the town.—Rob Hartill
