The placid town of Sereno Key is being rocked by a serial killer who is targeting black men, leaving his victims marked with black paint. When police zero in on a suspect, his wife hires Louis to help clear him. Lured from Michigan to work as a PI by his ex-boss, Louis joins forces with a novice FBI profiler, Emily Farrantino, and they quickly discover these are no ordinary hate crimes and that Sereno Key is only the latest stop on a psychopath's road tour from hell.
