A group of friends decides to go on a winter snowmobile trip to unwind and reconnect. The isolated and scenic Montana wilderness seems like the perfect getaway until they stumble upon a remote, abandoned monastery. Inside, they find evidence of past occult rituals and unwittingly revive a malevolent force. Strange occurrences begin to disrupt their weekend, with one friend after another falling victim to horrifying, supernatural events. Desperation turns to terror as they realize they are being hunted, and the once-idyllic setting becomes a frozen nightmare.

Their attempts to leave the area are thwarted by worsening weather and mechanical failures, forcing them to take refuge in the eerie monastery. The friends struggle to make sense of the escalating madness while grappling with their own growing panic and distrust of one another. As the force's power intensifies, they uncover dark secrets about the monastery's history and the horrific fate that befell its previous inhabitants. Their only hope for survival lies in confronting the ancient evil, but time is running out, and not all of them may live to see another dawn.
