The zombie apocalypse of the future started in the Wild West.
Confederate veteran Ezekiel Cool leads a quiet life as small town sheriff in the Dakota Territory. Haunted by nightmares of wars gone by, he just wants to be left alone.
Then a man steps off a riverboat and bites the town drunk, who then bites someone else, who then ... Ezekiel is thrust back into the role of soldier again. Now he just wants to survive the night.
Has it all: funny, sad, and scary with likeable, more-than-capable good guys along with bad guys.
