In the year 1959, a frightened and disturbed little girl named Lucinda was in school when her class was drawing up pictures for the school's time capsule, but Lucinda drew up a weird system of numbers and even was scratching at the school janitor's door. Now, 50 years later, John Koestler an astronomer and a professor at MIT is at his son, Caleb's school to open up the time capsule and was given Lucinda's system of numbers. When John was looking at the numbers, he quickly realized that it was some type of code that predicted the month, date and year of a specific disaster, and how many people died in that particular disaster. After witnessing a plane crash at Logan International Airport, and saving people from a freak New York Subway accident, John realizes that the last disaster on the code is the end of the world when one of the Sun's solar flares will scorch the Earth. Meanwhile, Caleb witnesses strange people who stalk him, and a little girl named Abby and her mother named Diana. Now, John and his son Caleb along with Abby and Diana must save as many people as they can from the Sun's solar flares while trying to find out about the strange people.
