As the Robinsons prepare to depart from their planet, they encounter a young alien named J-5. They decide to take him along on their journey to reunite him with his home. Along the way, they stumble upon a peculiar ship that serves as an Earth "lighthouse" for wayward vessels. Excited at the prospect of gaining fuel and navigational charts, their joy quickly fades when J-5 discovers that they lack sufficient fuel to get him home. In a fit of rage, he conjures up a destructive creation from his imagination. Ultimately, J-5 opts to stay at the lighthouse, where he will be cared for by a kind, elderly keeper, while the Robinsons move on, reassured of his safety.
