Plot
Two military agents are taking readings on Mount Lincoln near the town of Ascension. There is a quake and the woman, Agent O'Neil, dies with marks on her face. The man, Agent McKewan, also dies after being crushed. Elsewhere, a man is injured in a work crew and dies for no apparent reason. It later appears the quakes on the mountain are producing a layer of carbon dioxide gas, suffocating those who descend to its altitude. A woman named Emily, studying Mt. Lincoln, visits the mountain to repair two machines.
In the adjacent town, an old man named William is considered an eccentric for believing that the mountain contains Behemoth. Emily meets with William's son and her old friend, Thomas. Satellite images show movement under the mountain, which they attribute to volcanism. Thomas's sister Grace and her boyfriend ascend the mountain, and Thomas is persuaded to go as guide to government agent Jack Murray. They meet Emily, who is running because part of a mountain suddenly exploded; whereas Grace and her boyfriend are startled by a monstrous eye and accompanying tentacle.
After she and Thomas have discovered Agent O'Neil's body, Emily has persuaded the Sheriff to evacuate the town, but Thomas and Emily ascend the mountain to look for the missing couple. They find Jack injured on the mountain, and Behemoth kills Jack immediately after revelation that the troubles at Mt. Lincoln were felt all over the world six months ago, and a missing box may be their only chance against Behemoth (lost when the agents were killed). William goes to the local diner to get the waitress, Zoe, to safety.
