Ultraviolet (2006)

Set in the late 21st century, a subculture of humans have emerged who have been modified genetically by a vampire-like disease, giving them enhanced speed, incredible stamina and acute intelligence, and as they are set apart from "normal" and "healthy" humans, the world is pushed to the brink of worldwide civil war aimed at the destruction of the "diseased" population. In the middle of this crossed-fire is - an infected beautiful woman - Ultraviolet, who finds herself protecting a nine-year-old boy who has been marked for death by the human government as he is believed to be a threat to humans.
