While she and her boss, Sheriff Jimmy Fleck (Jeffrey Combs), feel the pressure of finding the killer, their love affair begins to fall apart. Meanwhile, Zoe begins to team up with the autistic bloodhound trainer, Leroy Calhoun (Michael Berryman), and together they combine the dots between the killer and the strange clues.
