After Chet brings home a hippie, Harry does everything he can to get him to leave. Meanwhile, Ralph and his Company B anti- communist force track the hippie, mistaking him for a communist. Once Harry decides to beat the hippie at his own game, he becomes the new target of Ralph and his cronies. They construct the ""Great Wall of Elm Street"" in an attempt to save the rest of the neighborhood from being exposed to these ""traitors"". The media attention, caused by this, results in the hippie leaving.
