"Lost in Space" is set to the year 1997, when the United States sends the Robinson family on a mission in outer space to the planet Alpha Centauri, which is thought to support life. However, while trying to sabotage this mission, Dr. Smith is accidentally trapped inside the ship, "Jupiter 2". To try to return to Earth, Dr. Smith ends up changing the ship's course, causing him and the Robinsons to become hopelessly lost in space. Because the series was unexpectedly canceled, the story was never finished. In the last episode, Dr. Smith and the Robinsons are still lost in space, stuck in a junkyard.
