Paul Callan is about to embark on the most amazing journey of his life. As an investigator of modern miracles, Paul (Skeet Ulrich) finds the result is always the same: a mundane explanation and a crowd of disappointed believers. With his faith dwindling everyday, his only belief is "we're all alone down here." Then something happens to change all that. Paul's life is saved by Tommy Ferguson, a young boy with the power to heal. But Tommy pays for the miracle with his life. Just before Tommy dies — and Paul is given a second life — they both see the words "God Is Now Here" written in Paul's blood. And suddenly, nothing will ever be the same. As Paul tries to understand what has happened to him, he joins forces with Alva Keel (Angus Macfadyen), a former Harvard professor and current investigator of the paranormal. Both men feel the other possesses the key to a larger mystery — the rapidly growing number of "strange occurrences" that happen all over the world and which may point to a frightening and deadly "large event" that is coming… Now, with the help of former police officer Evelyn Santos (Marisa Ramirez), these investigators will go anywhere and do anything to uncover the unexplained, and try to find a solution to the coming "darkness"… before it's too late.
