There’s a night stalker loose in Sioux City who believes she’s on a mission from God. Woodbury County prosecutor Hillary Reed believes all things are possible with God—including putting her together with an unlikely significant other, Sioux City Sentinel-Leader reporter Tom Kingman. But when a killer named Gabrielle starts sending Tom handwritten notes claiming to be God’s avenging angel, Hillary concurs with Tom’s assessment: “It’s more likely Gabrielle has been dropping acid while reading Leviticus” than getting divine direction to slash some throats. Meanwhile, Hillary faces professional challenges, including a nagging feeling that she’s prosecuting the wrong man for murder. When Gabrielle starts to show a personal interest in Tom, pressure from Tom’s pious stalker and Hillary’s high-profile court case builds until it triggers a bombshell revelation that could blow Tom and Hillary apart.
