A trio of mismatched mercenaries is hired by a young woman for a deceptively simple task: check in on her nephew, who may have been taken against his will to a remote New Mexico backwoods settlement called Little Heaven. Shortly after they arrive, things begin to turn ominous. Stirrings in the woods and over the treetops — the brooding shape of a monolith known as the Black Rock casts its terrible pall. Paranoia and distrust grips the settlement. The escape routes are gradually cut off as events spiral towards madness. Hell — or the closest thing to it — invades Little Heaven. The remaining occupants are forced to take a stand and fight back, but whatever has cast its dark eye on Little Heaven is now marshaling its powers...and it wants them all.
