Ana goes home to her peaceful suburban residence, but she is unpleasantly surprised the morning that follows when her husband is brutally attacked by her zombified neighbor. In the chaos of her once picturesque neighborhood, Ana flees and stumbles upon a police officer named Kenneth, along with more survivors who decide that their best chances of survival would be found in the deserted Crossroads Shopping Mall. When supplies begin running low and other trapped survivors need help, the group comes to the realization that they cannot stay put forever at the Shopping Mall and devise a plan to escape.
