The teacher, John Koestler (played by Nicolas Cage), discovers that the time capsule contains a letter with a string of numbers that seem to have no significance. However, as he investigates further, he discovers that the numbers predict major disasters and tragedies, including specific dates, locations, and death tolls.
As John delves deeper into the mystery, he realizes that the numbers are connected to his own family, and that they may be integral to preventing the impending disaster. He meets and collaborates with Diana Wayland (played by Rose Byrne), the daughter of the girl who wrote the letter in the time capsule, and together they work to uncover the truth behind the numbers and the events they are predicting.
As John and Diana race against time to prevent a catastrophic event, they are met with numerous obstacles, such as government agencies and other individuals who want to keep the truth hidden. Their quest eventually leads them to a shocking revelation about the nature of the numbers and their connection to the future of humanity.
The movie explores themes of fate, predestination, and the role that individuals play in shaping the future. It received mixed reviews from critics but was a box office success, grossing over $180 million worldwide.
