Former soldier Bo Bellam is called out to a small east Texas church to help an old friend. What he discovers there is unimaginable: his friend is dead, and the corpse is in a strange and grotesque condition. When the dead body inexplicably walks itself out of a funeral home and disappears, Bo knows he must act quickly. He enlists the help of his friend, Dave Black, and together they embark on a hunt to find the corpse. Along the way, the duo reluctantly joins forces with strangers already investigating several unusual deaths. One by one, the dead turn into the undead. Desperate to stave off a zombie apocalypse, Bo assumes the role of zombie hunter. What Bo doesn’t realize is the people around him have dark secrets, and someone is watching his every move. With every swing of his axe, Bo unwittingly drags himself and his friends closer into the clutches of an unknown and dangerous enemy. And it's just the beginning.
