Deepest night, Montana....
An eerie light proclaims the arrival of a mysterious watcher in the woods. And one solitary man begins a desperate battle against something unknown - and unknowable.
Broad daylight, Los Angeles....

Fate will lead this family to an isolated Montana ranch, but their sanctuary will become their worst nightmare. For there they will face a chillingly ruthless enemy, from which no one - living or dead - is safe.
