A young girl, Wen, and her adoptive fathers, Eric and Andrew, are vacationing at a remote cabin in the woods, seeking a peaceful escape from their busy lives. Their idyll is violently interrupted when four strangers, led by the enigmatic Leonard, arrive and take the family hostage. The intruders are not typical criminals; they are seemingly normal individuals from diverse backgrounds, including a nurse, a chef, and a construction worker, who share the same urgent message that they've been compelled to deliver due to disturbing visions.

The strangers inform the family of an impending apocalypse and present them with a harrowing decision: in order to prevent global catastrophe, the family must willingly choose to sacrifice one of their own. As the tension mounts, Eric and Andrew are faced with the unimaginable task of parsing reality from madness. They grapple with the sincerity and sanity of their captors while desperately seeking a way to protect their daughter. The narrative thrives on a blend of psychological tension and moral dilemmas, confronting the characters—and the audience—with questions about faith, sacrifice, and the nature of true threats. The sense of urgency is amplified by a ticking clock and the possibility that there might be truth to the intruders' claims, forcing the family to make an impossible decision under the most extreme of circumstances.
