After a bad day at school, David (Matthew Broderick) beats the blues with an afternoon of hacking. First, he sticks it to the Man by changing his grades in the high school's computer system. Then he tries to get the jump on a new computer game. Problem is, he doesn't hack into a computer game company, he hacks into a military supercomputer. Uh-oh, I think that's the sound of the Cold War melting.
