100 years in the future, planetary colonization missions have begun as a necessity to help secure the survival of the human race. The first of these missions on a spacecraft known as Ark One encounters a catastrophic event causing massive destruction and loss of life. With more than a year left to go before reaching their target planet, a lack of life-sustaining supplies and loss of leadership, the remaining crew must become the best versions of themselves to stay on course and survive.

When Sheriff Roy Pulsipher finds himself in the afterlife, he joins a special police force and returns to Earth to save humanity from the undead.
