A group of hikers realize they’re being shadowed by something massive, intelligent, and disturbingly silent as it tests their formation and tries to isolate one of them. A grieving teacher retreats to a remote cabin to recover from a breakup—but her third night is shattered by an ungodly howl and a deformed figure staring through the window. A solo hiker wakes in the night to the pressure of something huge leaning into the side of his tent—then sees a clawed hand press through the nylon. When five black claws tear straight through the wall, he panics.
