Robert Neville (Will Smith) is a brilliant scientist, but even he could not contain the terrible virus that was unstoppable, incurable... and manmade. Somehow immune, Neville is now the last human survivor in what is left of New York City... and maybe the world. But he is not alone. He is surrounded by "the Infected"?victims of the plague who have mutated into carnivorous beings who can only exist in the dark and who will devour or infect anyone or anything in their path.
