The morning it all started, newspaper reporter David Harwood had plenty to worry about. A single parent with no job, forced to return with his young son to the small town of Promise Falls to live with his parents, the future wasn't looking too rosy. So when his mother asked him to look in on his cousin Marla, who was still not quite right after losing her baby, it was almost a relief to put the disaster his own life had become to one side. The relief wouldn't last long. When he gets to Marla's house he's disturbed to find a smear of blood on the front door. He's even more disturbed to find Marla nursing a baby, a baby she claims was delivered to her 'by an angel.' And when, soon after, a woman's body is discovered across town, stabbed to death, with her own baby missing, it looks as if Marla has done something truly terrible.
