A spider escapes from an isolated desert laboratory experimenting in giantism and grows to tremendous size as it wreaks havoc on the local inhabitants.
In Desert Rock, Arizona, a disfigured man is found dead and identified by Professor Gerald Deemer as his assistant and friend Dr. Eric Jacobs, who would suffer from acromegalia. The country doctor Matt Hastings is puzzled with the mysterious disease and decides to investigate further about acromegalia. Professor Deemer omits that Dr. Eric Jacobs and Dr. Paul Lund were researching with him a nutrient to increase the food supply in the world and they have been affected by the experiment. Soon Paul Lund, who has also been affected and is mad, breaks and sets the laboratory on fire and a huge tarantula escapes. Meanwhile, the gorgeous Stephanie "Steve" Clayton arrives in town to work with Dr. Jacobs, and Dr. Hastings drives her to Professor Deemer's house in the desert. She is hired by Deemer and she finds that he is sick. When cattle bones are found in a farm, Hastings collects material and flies to a laboratory, where he learns that the sample is of tarantula's venom. But the scientist does not believe that one tarantula could ever produce such quantity of venom. The doctor returns to Desert Rock sure that the species is part of Prof. Deemer's experiment and the locals are threatened by the dangerous tarantula.
