A little boy named David, goes out into the woods, and falls down into a ravine. He wakes up and discovers that he is in the future. So, he goes back home, but nobody is there that he recognizes. He eventually finds his parents, which are visibly older now, especially his brother, who is a lot older now. He then finds a spaceship in a nearby hanger and a robot inside the ship that operates it. It recognizes David and takes him on a trip around the world. David eventually decides that he can't stay in the future anymore and asks the robot to take him back to 1978. The robot agrees and takes him back.
