Ally Sheedy

High school student David Lightman has a talent for hacking. But while trying to hack into a computer system to play unreleased video games, he unwittingly taps into the Department of Defense's war computer and initiates a confrontation of global proportions. Together with his friend and a wizardly computer genius, David must race against time to outwit his opponent and prevent a nuclear Armageddon.

Five high school students from different walks of life endure a Saturday detention under a power-hungry principal. The disparate group includes rebel John, princess Claire, outcast Allison, brainy Brian and Andrew, the jock. Each has a chance to tell his or her story, making the others see them a little differently -- and when the day ends, they question whether school will ever be the same.
