Charlie, a young boy who reportedly grew up alone with only computer banks for company and teachers, is picked up by the crew of a starship and is transferred to the Enterprise for a trip to a starbase. During the trip, Charlie begins to learn more about human relationships and becomes infatuated with Yeoman Rand. When she tells him that he is too young for her, Charlie is enraged and begins to do away with members of the crew who he feels have been condescending to him - including Captain Kirk.
