Dawn of the Dead (2004)
Remake of George Romero's horror classic. An unexplained plague has decimated the world's population and yet...the dead aren't dying. They've become zombies, stalking endlessly in a constant quest to feed on the flesh and blood of the few remaining living. A ragtag group of desperate survivors in a Wisconsin town seek refuge in a large indoor shopping mall, where they must learn not only to protect themselves from the ever-increasing zombie horde, but also to co-exist with each other as one of the last bastions of humanity. Sealed off from the rest of what used to be the world, the group uses every available resource (both within and without) in their against-all-odds fight to remain alive and human.
