Residents of Los Angeles go about their day unaware that a mysterious event is about to change their lives. FBI agents Mark Benford and Demetri Noh are in a car chase; Benford's physician wife is in the middle of surgery; and Benford's friend Aaron Stark works on power lines high above the ground. Suddenly, something causes everyone in the world to black out for just over two minutes. During that time, each person sees a series of events in his or her own future -- some good, some bad, some apparently nonexistent. As people begin to piece together their visions on a worldwide website, Mark and Demetri use the information to try to pinpoint the cause of the blackout, and people are still trying to determine whether destiny can be changed, and what effect those changes may have on others.
