Friends suggest that Anna go on a hike to a beautiful lake—to unwind and forget. The girl isn’t thrilled by the idea, but still agrees, not really expecting anything good. Her intuition doesn’t fail, and the weirdness starts right after their car pulls onto a forest road. A thick, impenetrable fog wraps everything around, forcing the travelers to stop; and when, in a mysterious way, one of the girls disappears, they realize they won’t be able to leave just like that anymore… What or who is really lurking inside the foggy forest? What secrets will Anna have to uncover, and what sacrifices will she need to make, to save her friends—and herself?! Contains profanity.
