One month after the zombie virus destroyed the United States of America, Dakota Travis and his best friend, Steve Earnest, are struggling to survive. With a dwindling food supply and a violent gang encroaching on their territory, there is little they can do but run.
After fleeing into the wasteland of South Dakota, and nearly losing their lives to a zombie horde in the process, they encounter the last remnants of the United States military, and take refuge within an abandoned insane asylum.
Surrounded by the undead, tensions run high. Food is in short supply. Shelter may only be temporary. The commanding officer is going insane. And once the corporal, sir Jamie Marks, begins to make romantic advances toward Dakota, his and Steve's safety may not be completely guaranteed.
