Peck's producer shows a trailer of the film Peck was supposed to start making, "The Marked", to Tom and Diana, and it paints a new, frightful picture: In the future the 4400 are supposed to prevent, exists a group of powerful individuals who like their time just the way it is and have irrevocably replaced the minds of ten important persons of the present time with the minds of their agents.
