After seeing retired astronaut Brigadier General
Jim McDivitt speak about a UFO he saw while on a space mission, Peter and Bobby have UFO on the brain. That night, they believe they see a UFO in the sky. Without other witnesses, others are either uncertain or are skeptical as to Peter and Bobby's assertion. Peter and Bobby feel they need proof, and want to sleep outside in the back yard and take photographs if and when the UFO shows up again. Lo and behold, what Peter and Bobby saw the previous night comes back and they are able to take photographs of it. After the photographs are developed, Mike and Carol are still uncertain about what is on the photos, so Mike decides to call in the air force for their expert opinion. The visit of the air force's investigating Captain McCartney, who doesn't believe in UFOs, indirectly makes Peter and Bobby's UFO appear again, but it with a more down to earth explanation.
