Plot
Jack Flynn is driving down a highway at night looking at a bracelet he bought his teenage daughter Carol for her birthday, when his truck hits a massive silky thread. The next morning, Carol is concerned that her ne'er-do-well father did not come home the night before. She convinces her boyfriend Mike to assist in a search. They find his crashed truck and the bracelet. Thinking he may have taken shelter in a nearby cave, they investigate. In the darkness of the cave, they step off a ledge and fall onto the gigantic web of an enormous tarantula, which emerges and chases them out of the cave.
The sheriff does not believe Carol and Mike about the giant spider, but their science teacher, Mr. Kingman, persuades him to return to the cave with large amounts of DDT. They find Jack's body, drained of fluids, and spray DDT throughout the cavern to flush out and then kill the spider. The apparently lifeless body of the spider is taken back to town to the high school gym, where Kingman wants to study it, concerned that whatever conditions created it may produce a whole race of giant spiders. A group of teenagers uses the gym to practice rock and roll numbers they are going to play for a school dance. The music awakens the spider and it crashes through the wall of the gym. The janitor, stopping to call the teacher, is killed.
The spider terrorizes the town, killing a number of people before heading to Kingman's house, attacking his wife and son. Kingman, in his car, gets the spider's attention and lures it outside of town before escaping and doubling back to confirm that his wife and son are safe.
The spider is spotted returning to its cave.
