A church group's yearly retreat becomes a nightmare when they stray into a forbidden stretch of the Ozark woods, where a unseen killer begins eliminating them one by one. All eyes turn to Ricky, the group's resident rebel—but the true danger is unimaginably worse. Trapped deep in the forest amid a maze of webs, they're stalked by a monstrous prehistoric spider that tracks its prey by vibration. With each footstep potentially fatal, survival demands absolute stillness. Megan must rally the remaining survivors and lead them out before they're all consumed.
