On the remote planet Ryushi, a small ranching community becomes an unwilling participant in a deadly ritual: extraterrestrial Predators have seeded Ryushi with Alien eggs in order to create the ultimate hunt. But what the Predators don't know is that an Alien queen egg is amongst those they've sent as potential hunting stock. When the Predators arrive, the hunters become the hunted amidst a monumental swarm of Aliens, and they may need to turn to the very same humans they regard as little more than potential trophies to give them any hope of survival.
