Unbeknownst to humans, there is a thriving, technologically sophisticated society of Martians living below the surface of Mars. The Martians Supervisor, while observing Earth, sees a mother persuading her son, Milo, to do his chores. The Martians decide to bring her to Mars, where her "momness" will be extracted and implanted into the next generation of nannybots. Meanwhile, Milo - who doesn't like following the house rules and doing chores and has been grounded (for flat out refusing to eat his broccoli by feeding it to Cujo the house cat (which is poisonous to cats) and deceiving her when he wanted to watch a movie on pay per view) as a result, tells his mother sarcastically that his life would be better without her, breaking her heart.
