A teenage computer whiz causes an international nuclear crisis when he hacks into the U.S. Defense Department "WOPR" computer system. A finely-wrought, edge-of-the-seat thriller. Academy Award Nominations: 3, including Best (Original) Screenplay, Best Cinematography. David (Matthew Broderick), a young hacker accidentally logs onto the Department Of Defense's network. Thinking that he's found a very cool new computer game manufacturer, David plays checkers, chess, tick-tack-toe and thermonuclear warfare... and has lots of fun until DOD operatives, realizing that their system has been tampered with, arrest him. But David's problems don't end there because, even though he is no longer on line, the computer continues to play the game. The DOD, however, believes that the computer is tracking Soviet missiles headed for the U.S. In an attempt to prevent disaster, David and his girlfriend, search desperately for the scientist who designed the system. All the while, the computer is searching for missle launch codes so that it can see what happens when WW3 starts for real.
