In 1959, as part of the dedication ceremony for a new elementary school, a group of students is asked to draw pictures to be stored in a time capsule. One mysterious girl fills her sheet of paper with rows of apparently random numbers instead. Fifty years later, a new generation of students examines the capsule's contents and the girl's cryptic message ends up in the hands of Caleb. But it is Caleb's father, professor John Koestler, who makes the startling discovery that the encoded message predicts with pinpoint accuracy the dates, death tolls and coordinates of every major disaster of the past 50 years. With the reluctant help of the daughter of the now-deceased author of the prophecies, John's increasingly desperate efforts take him on a race against time until he finds himself facing the ultimate disaster and the ultimate sacrifice.
