Consumer-grade drones now come with a "hands-free" setting that automatically directs the camera to follow you – in case you’re a surfer taking your next wave, a snowboarder back-flipping off a half-pipe, or a serial killer stalking your next victim. When a group of teens knock this drone out of the sky, they discover that it contains home movies of the killer’s brutal crimes. Now, they must race to expose the killer before becoming his next victims.
