Average American boy Chuck Murdock goes on a school outing to a nuclear weapons facility, where he learns about the destructive power that sits at the fingertips of the military. Knowing that the world could end with the push of a button, he protests against nuclear war by walking out on his Little League team during a game. Chuck's stunt ends up in the local paper, and as the story snowballs, basketball star "Amazing Grace" Smith decides to boycott sports, too.
