Spaceman Spiff finds himself on the planet surface. An alien approaches. In the blinding light, Spiff can't tell whether the alien is friendly or hostile. Mom comes in to yell at Calvin who's still sitting on his bed. She tells him to get ready for school. Spiff, being carried off by the alien, says that it's definitely hostile.

Calvin is tossed out the door. Mom tells him the bus will be by any minute. Get going! Spaceman Spiff, captured by the Zogwargs, is being transported to the labor camp. Our hero hatches a plan. He makes his break. Using the planet's weaker gravity, our hero is away like a shot. Mom looks out the window. She says she sees the bus, but why doesn't she see Calvin?

Spiff escapes! Dad asks if Calvin got on the bus. Mom says she didn't see. Dad mentions he saw someone darting behind a tree. They look and see it again. Dad asks if that's Calvin. Spiff inflates the emergency jet pack he keeps in his pocket. The Zogwargs have spotted him.

Mom gets on her coat and tells Calvin to get over there. Our hero blasts off on his jet pack. Another daring escape for the intrepid Spaceman Spiff. The Zogwargs are on rocket scooters. Spiff fires his death ray blaster. Calvin is throwing snowballs at Mom as she chases him. She tells him he's digging his own grave.

Mom drags Calvin back telling him he's in big trouble. She asks why he didn't get on the bus. Now she has to take him to school, and Dad will be late to work. She tells Calvin he's inconvenienced everyone and asks if he has anything to say for himself. Calvin tells the Zogwarg Queen to give him liberty or give him death. Mom turns from the steering wheel with teeth clenched. She tells Calvin not to tempt her. She also tells him to call her Mom.

Susie asks Calvin why he was late to school. Calvin tells her he was going to skip, but he got caught. When Susie asks how he got caught, Calvin tells her Mom had the wind for that final sprint. Susie asks if his Mom had to chase him. Calvin tells her he couldn't believe it when Mom cleared the hedge.
