One shot in the darkness. One moment of fear-fueled panic. And everything the expedition had built with the creatures comes crashing down.

In Episode Three, we witness the consequences of Jim McAllister's breakdown. Haunted by war, drowning his demons in homemade whiskey, Jim opens fire on a creature standing at the edge of the firelight—and triggers a siege that will test every man's sanity. What follows is a night of absolute terror. Rocks and branches hurled from the darkness. Horses screaming as they break free and scatter. 

The knocking—not the measured rhythm they'd grown accustomed to, but rapid, frantic, like a thousand hammers striking in unison. And underneath it all, a sound that cuts deeper than any threat: the unmistakable cry of grief.But the creatures don't attack. They could have. They demonstrate exactly what they're capable of—and then they wait.

Sam insists there's only one path forward: atonement. Each man must sacrifice something precious. Something that matters. What unfolds is a ritual of exchange that will determine whether the expedition lives or dies.The episode follows the group as they split—some returning east with the journals, others pressing deeper into territory no white man has ever seen.

Ancient forests where the trees are older than memory. Creatures walking openly beside them now, no longer hiding. And a meeting with the Wyandot tribe's keeper of history—She-Who-Remembers—who delivers a warning that chills to the bone: "No one who has entered that place has returned. Not because they kill everyone who enters. But because those who enter... change."
