Years have passed since Ali and her college friends last saw one another, and their trip to a secluded mountain cabin is supposed to be the perfect escape: no work, no phones, and no distractions. Just the great outdoors and the chance to reconnect. But a sudden snowstorm sweeps in overnight, turning their idyllic getaway into a nightmare.

When their friend David mysteriously disappears, it leaves them reeling and desperate for answers. Isolated from the outside world and consumed by fear, paranoia begins to seep in. Long-buried secrets and simmering resentments bubble to the surface, threatening to tear the group apart.

But the storm outside isn't their only danger. Someone is watching them—someone who knows their darkest secrets.

​​​​​​​On this mountain, there's nowhere to run... And no one can hide from what's coming.
