23-year-old Tessa, a broke Detroit waitress, can talk to rats, cockroaches, and flies. When a serial killer terrorizes the city, she turns the pests everyone hates into her own underground spy network. While police rely on cameras and forensics, Tessa follows whispers from the shadows to solve murders, uncover hidden bodies, and chase a killer who may be hunting her next.
