It had been years since Erica Thorne has gone to church. When her mother invited her and her friends to experience the outpouring of the Holy Ghost, she begrudgingly accepted. Erica hoped this trip soften her mother up enough to introduce her new wife, Kelly Tran. But, her church of family and friends had turned into monsters that wanted her dead. And, that was before the zombies had arrived. Soon Erica, Kelly, and a handful of survivors fight their way through hoards of the undead to destroy the Horn of Gabriel to save the world and stop a Second Coming.
