A father and daughter, Greg and Samantha, are on a camping trip in the wilderness when they are attacked by a bear. Seeking help, they stumble upon a seemingly tranquil commune deep in the forest. What initially appears to be a sanctuary soon reveals itself as the domain of a sinister cult led by the enigmatic Matgett. The cult believes in a cosmic entity known as the "Circle," which promises enlightenment but demands absolute devotion. As Greg is injured and incapable of leaving, the cult members tend to him and welcome Samantha enthusiastically, gradually drawing her into their beliefs.

As the days progress, Greg realizes the true nature of the cult and their nefarious intentions. His attempts to protect Samantha and escape with her become a labyrinthine challenge fraught with paranoia, shifting allegiances, and eerie rituals. Desperation mounts as he discovers that the Circle's influence extends far beyond the cult members, affecting minds and twisting perceptions. With escape routes dwindling and time running out, Greg must navigate this psychological nightmare to save his daughter and himself from an insidious fate.
