Betrayed by the mercenaries who once served him and abandoned to die on a scorching, monster-ridden world, the fugitive Riddick claws his way back to strength alone in the wild. To escape, he lights a distress beacon that lures two rival crews of bounty hunters, then turns their greed into a trap. As a deadly storm unleashes swarms of alien predators, hunters and hunted must fight side by side to survive the night. David Twohy strips the saga back to its lean survivalist roots, delivering a gritty, pulpy sci-fi thriller built around Vin Diesel's growling antihero.
