When the zombie apocalypse arrives, groups of survivors band together to defend themselves at any cost. Unfortunately for the remaining few, zombies have evolved into different species altogether and exist not just in this dimension but in a dimension of their own. With little hope, the humans gather strength for one last chance at saving their world in this intensely twisted anthology.

Mark Fisher disappeared from his home in a brilliant flash of blue light almost two years ago. His friend Seth Hampton was the last to see him alive. Now a string of grisly, violent murders leads Seth to believe that Mark is back, and something evil is living inside of him.
