A group of misfit high school students stumble upon an ancient Aztec death whistle. They find that when they blow the whistle, the terrifying sound it emits will invoke their future deaths to hunt them down. As the body count rises, the friends investigate the origins of the deadly artifact in a desperate effort to stop the horrifying chain of events that they have set in motion.
