Rattlers is a 1976 horror film starring Sam Chew, Elisabeth Chauvet, Tony Ballen, Dan Priest, Ron Gold, Darwin Joston, and Gary Van Ormand.

When two young boys are savagely attacked and killed by a legion of rattlesnakes in a small California desert town, the local sheriff calls upon herpetologist Dr. Tom Parkinson, a Los Angeles college professor, to discover why the snakes are displaying abnormal aggression and swarming behavior.

As more people in the desert town are killed by the vicious rattlesnakes, Parkinson's and Bradley's investigation leads them to a nearby army base, where the commanding officer, Colonel Stroud, seems strangely reluctant to help them.

Shortly afterward, Palmer and Woodley, two soldiers on night patrol, stop to change a flat tire on their jeep and are killed by a horde of rattlesnakes.
