Fifty years after it was buried in a time capsule, a schoolgirl's cryptic document falls into the hands of Caleb Koestler, the son of professor John Koestler (Nicolas Cage). John figures out that the encoded message accurately lists every major disaster from the past five decades, and predicts three future calamities -- one a global cataclysm. When his warnings fall on deaf ears, John enlists the help of the prophetic author's daughter and granddaughter to try to avert the ultimate disaster.
