When three campers witness an alien mothership descending on their town and turning the population into "Altered" human beings, they team up with a reclusive stranger who offers to guide them to safety. As they're chased deep into the forest and one of them becomes infected, they realize there's nowhere to hide from the Altered horde that seems intent upon finding and assimilating them.
