Daybreakers

Set ten years into the future, most of the population has been infected and become vampires. They prey on the few remaining humans, or buy blood to satiate themselves. One of the top scientist at the blood supply company gets involved with the human underground, who are fighting for the survival of their species. One of them has developed a cheap antidote for the problem, but naturally the blood supply company does not want this to become available as it will destroy their business. This sets the stage for the hunting and killing of the humans and vampires, as the two sides embark on an epic battle to determine the dominant species once and for all.
