In the wake of a mysterious plague that reanimates the dead, society collapses into chaos as the infected, now relentless zombies, prey upon the living. Ana, a nurse, wakes to this nightmare when her suburban life is shattered by her husband's horrific transformation after a bite from a child. Fleeing her home, she crashes into a small group of survivors: a stoic police officer, Kenneth; a street-smart salesman, Michael; a pregnant woman, Luda, and her partner, Andre; and others equally shocked and unprepared for the apocalypse unfolding around them. The group takes refuge in a nearby shopping mall as a temporary sanctuary, but they soon realize the illusion of safety is short-lived.

Barricading themselves inside the mall, they struggle not only with the continuous onslaught of the undead but also with the dynamics of a rapidly forming society under siege. Tensions rise as they grapple with dwindling supplies, the need for defiant stands against the invaders, and the realization that to survive, they must plan a future beyond the mall's false security. As the undead evolve and their attacks intensify, the remaining humans must adapt and make harrowing decisions to avoid becoming part of the growing horde of zombies that now dominate the world outside.
