Cancel your camping plans, because a new "Blair Witch" trailer is here to scare you away from the woods.

Released today by Collider, the preview makes the upcoming horror flick look every bit as terrifying as its predecessors, 1999's "The Blair Witch Project" and 2000's "Book of Shadows: Blair Witch 2." The film follows James (played by James Allen McCune) and a group of fellow college students as they take a trip into Maryland's Black Hills Forest to see what they can find out about the mysterious disappearance of his sister. There, they get more than they bargained for, and naturally, it is the stuff of nightmares. According to the film's official synopsis, "the group is visited by a menacing presence," and "they begin to realize the legend is all too real and more sinister than they could have imagined."

The footage is just as eerie as that sounds. A word to the wise? If you ever come upon the entrance to a creepy underground tunnel and you think, "I don't want to go in there ... let's not go," go with your gut.

"Blair Witch" stars McCune, Callie Hernandez, Brandon Scott, Valorie Curry, Corbin Reid, and Wes Robinson. The film hits theaters on Sept. 16.
