WarGames

A teenager, bored by traditional high school subjects like biology but fascinated by computers, accidentally taps into the Pentagon's top-secret computer...the USA's NORAD system. He starts what he innocently believes is a computer game called Global Thermonuclear War, but the game is real. The Pentagon's best minds cannot shut down or reprogram the supercomputer that is readying a missile attack against the USSR, and thereby unleash Armageddon. The teen and his girlfriend attempt to aid the helpless Pentagon and, in a frantic race against a ticking doomsday clock, try to persuade the computer to end the game.
