A documentary about the cult television favorite Mystery Science Theater 3000.

Dr. Clayton Forrester figures he can rule the world if he deadens his subjects' brains by making them endure terrible movies. Exploiting his access to nearby satellite-dwellers Mike Nelson and his robot pals, Crow T. Robot and Tom Servo, Forrester makes them watch "This Island Earth", a cheesy 1950s spaceship film. But when Mike and friends make funny comments throughout the movie and others that follow, Forrester's plan looks increasingly flimsy.
