Rick is the sheriff of a peaceful small town. But when a mysterious virus turns people into zombies, he loses almost everything. Stranded in the middle of a hostile new world, he tries to find his wife, son and best friend and to figure out what's really happening. Along the way, he meets other survivors of the apocalypse and becomes their leader. They trust him and put their lives in his hands. From that moment on, he turns into their savior and protector. Food, water, and shelter are the most valuable things now, and instead of joining forces, different groups of people fight each other for the resources. Rick is still determined to find his loved ones.
