Taking time off from Lost in Space, Billy Mumy guests as Custer Jamison, an 8-year-old neighbor boy who considers astronaut Tony Nelson (Larry Hagman) as his personal hero. Dropping in unannounced at Tony's house, Custer witnesses Jeannie (Barbara Eden) floating about in mid-air. When the kid tells his parents about this, Dr. Bellows (Hayden Rorke) offers to psychoanalyze Custer, hoping to prove once and for all that something very strange is going on the Nelson household. ~ Hal Erickson, Rovi
