A group of friends gathers in a remote cabin for a peaceful Thanksgiving dinner. Their holiday takes a horrifying turn when a stranger arrives, injures himself at their door, and cryptically warns them before dying suddenly. The friends are thrown into a panic, debating whether to seek help or stay put. Tensions rise as they struggle with the decision, only to realize that the cabin's phone lines are dead and they are completely isolated from the outside world. Paranoia begins to set in, and strange occurrences within the house further fracture their trust in each other.

As the situation escalates, each friend starts experiencing personal terrors that seem inexplicably linked to the mysterious stranger's last words. They uncover bizarre clues that suggest they may be part of a grotesque experiment or confrontation with otherworldly forces. Desperation drives them to the brink as they try to make sense of the chaos, but their attempts are hindered by eerie distortions of reality and growing mistrust among them. The night spirals into a waking nightmare, leading the group into a battle for survival they may not be prepared to face.
