A relaxing trip to the woods turns into a nightmare of cosmic proportions when a group of young friends are tormented by malevolent extraterrestrials. As a young girl, April spent much of her childhood at her family's cozy, secluded cabin. Now April (Brittany Allen
) is all grown up, and life didn't exactly turn out how she hoped it would. In the aftermath of her parents' divorce, April ventures back to that scenic cottage with a group of her closest friends. But just as those nostalgic memories come rushing back, the group watches in amazement as a massive fireball plummets to the Earth nearby. Curious, April's boyfriend (Freddie Stroma
) leads the group into the woods for a closer look. What they discover out in the darkness leaves them more terrified than they could have ever imagined; a UFO has crashed, and all evidence suggests that the otherworldly survivors are watching them from the trees. By the time April and her friends learn that the U.S. government struck a deal with the aliens after Roswell it's already too late, because the curious college students have broken the cardinal rule of the secret pack: Never, under any circumstances, engage the visitors because once you do, you become their prey.
