The Atlantic & Pacific Railroad is one of many lines aggressively pushing west. Thousands of workers, security officers, and following merchants make the impossible happen, pursuing their manifest destiny. History and pain runs deep in the hearts of many and violence is always near. Delays at a canyon in northern Arizona have turned a normal work camp into a bustling small town almost overnight. The town of Cañon Diablo quickly becomes a haven for debauchery, sin, and lawlessness. Those in charge, led by the stalwart Lieutenant Harris, do their utmost to maintain civility and ensure the rail line is finished in the face of a pending blizzard. The volatile situation is made worse when a creature begins killing people. Desperate and frightened, the people in town must fight the elements and their own prejudices if they hope to survive and put a stop the blood-thirsty horror.
