Live...work...play...die.

South Haven is the premier mixed-used community in metro Atlanta - a vibrant place where old-fashioned country living gets a modern update. There’s the town square where residents watch family movies on the lawn on warm summer nights.

The corner market stocked with organic foods. The bakery with fresh coffee and Wi-Fi. The stately homes on shaded, gently winding streets. The water park where children splash, laugh, and run.

There’s also something deadly lurking.

The first incident is dismissed as an aberration: a college student goes berserk and hacks his family to chunks with a machete. But a day later, a young woman riding her bicycle is chased through the streets by her own neighbors. Then, a teenager takes a deadly joyride, using his pick-up truck to mow down everyone in sight.

As the incidents pile up, the only thing they share is that each person launched into an inexplicable, uncontrollable frenzy.

Fearful residents huddle inside, uncertain whom to trust, anxiously watching one another for clues of where the terror might strike next. Together with Dr. Hannah Bailey, a brilliant CDC scientist dispatched to investigate the threat, Deacon teams up with a motley crew of neighbors, and they hatch a desperate plan to find out answers and stay alive.

But the spreading menace might not have arrived by accident...
