Thrown five years in the future, Hiro and Ando discover that people with extraordinary abilities are not only widely known about -- after the destruction of New York City and the deaths of millions -- but are being registered, imprisoned, hunted and even killed as "terrorists." As the President takes his first step towards a "final solution," the pair get swept up in what could be the "Heroes" final battle and encounter a range of new and darkly familiar faces. If they survive the experience, can they still get back to the present and save the world?

Poised to become a member of Congress and maybe more, Nathan considers the cost to those he loves, along with his mother's advice and Linderman's prophecy. As he prepares to face Sylar to the death, Hiro learns of his linage from his father. While various "heroes" fatefully arrive in New York City, Peter and Claire attempt to leave the city before the foretold explosion. H.R.G. and Matt learn the surprising truth behind the tracking system used on people with special abilities.
