Times Square, New York City. The first ever mass séance is broadcasting live on the Sunrise morning show. If it works, the spirits of the departed on the other side will have a brief window-just a few minutes-to send a final message to their grieving loved ones.

Clasping hands in an impenetrable grip, three mediums call to their spirit guides as the audience looks on in breathless anticipation. The mediums slump over, slackjawed-catatonic. And in cemeteries surrounding Manhattan, fragments of old corpses dig themselves out of the ground....

The spirits have returned. The dead are walking. They will seek out those who loved them in life, those they left behind...but they are savage and they are hungry. The horror spreads quickly, droves of the ravenous dead seeking out the living-shredding flesh from bone, feeding . But a disparate group of unlikely heroes-two headstrong college rivals, a troubled gang member, a teenage pop star and her bodyguard-is making its way to the center of the nightmare, fighting to protect their loved ones, fighting for their lives, and fighting to end the madness.
