WarGames 1983
David Lightman is a curious young man with good relationships with those around him. He believes he has accessed a company-owned computer system and starts playing a computer game he finds there. Unbeknownst to him, what he thinks is a game is actually a simulation that controls nuclear missiles in the American military defense system. Thinking he is playing a simple war game, the young hacker finds himself in the midst of the Third World War.
