Micah Bishop doesn't believe in miracles -- until a derringer-packing nun busts him out of jail. But it's not Christian charity that's driving Sister Genevieve -- she wants Micah to take her to a place called the Valley of Fire, deep in the most lawless and perilous part of New Mexico Territory. It was here where an order of nuns met their Maker, and it's Sister Genevieve's mission to see that they are given a proper funeral.
