At 3:02 a.m. in Savannah's historic district, a hideous, shuffling figure crosses the town square under the eye of a bank security camera. The next morning, FBI agent Ella Wilson is summoned to a nearby house where a man lies dead and partially devoured. Her partner reminds her that zombies aren't real, but as head of the Paranormal Crimes Unit, tasked with cases that seemingly defy scientific explanation, Ella knows to keep her mind as open as the victim's chest cavity. With the security footage already leaked online and racking up views, the pressure to explain the inexplicable is mounting.
