When the world is coming to an end because of an apocalypse like no other, who do you call? No, not our infamous ghost busting heroes. The man you want to call is Larson Pagan. The hard-working insurance agent has quite the second job that will help the world when everything goes south. When things grow dark and shadow demons decide to rip through the veil between the living and the dead to take over the world, it's up to Larson and his fellow paranormal investigators to put them back into Hell where they came.
With the help of paranormal investigators and non-paranormal investigators alike, Larson works against the clock to find out who has started the horrors and put an end to their terror. But as he works to save the present and the future, the past comes back to haunt him. Will he be strong enough to work past the trauma of his past in order to save the world?
