Arachnophobia

A group of researchers is on a research expedition to Venezuela. Upon a routine trapping of insects, the researchers find two stunned spiders in their traps, and they study these insects that are unlike any spiders they have ever seen. One spider escapes and kills a researcher, then hitches a ride back to the researchers' hometown, Canaima, California. Dr. Ross Jennings has just moved in there and is deathly afraid of spiders. Now, the Venezuelan spider has reached the U.S., and has begun to dominate the town. Soon, people who appear completely healthy start to die suddenly. Only after the death of the town's only other doctor does Jennings realize that a spider might be causing the deaths. He sends his assistant to Canaima, only verifying that the Venezuelan spider was involved. He informs them that the Venezuelan spider plans to take over its new area by creating reproductive offspring with a domestic house spider. Now, it's a race against time before the Venezuelan spider manifests the town, and eventually the entire country.
