Lost in Space: Will is conducting an experiment in a cave and captures a man who claims to be the man who controls time for the entire universe. This "Time Merchant" takes Will, Professor Robinson, Smith and the Robot, to his secret lair. From there, Smith uses the Time Merchant's time machine to return himself to Earth on the day the Robinson's departed, with the objective of not sabotaging the Jupiter 2 mission and letting the Robinsons go on their way to Alpha Centauri. The Time Merchant then announces that if Smith does not get on the Jupiter 2, the ship will not fly off course and will therefore be destroyed by a collision with an asteroid several months after liftoff.
