The sole survivor of terrible train wreck, David Dunn, a security guard, is contacted by Elijah Price, a mysterious stranger who tries to convince David that he has a special gift.

Investigative reporter Rowena Price poses as a temp worker and an online seductress to prove that advertising executive Harrison Hill killed her friend, with whom he was having an affair.

For one special security guard, tracking people down is a paranormal sort of hobby. Able to use his rare abilities to find people, David Dunn is suddenly given a job that seems more daunting than all the others before it. He'll need to find Kevin Wendell Crumb, and time is of the essence. But part of the problem is that Crumb is an extremely disturbed man and with 24 personalities, he's a lot more complicated than the others Dunn has found.
