Scientists inside a science base in the Moon conduct a variety of humorous experiments. We see a cat chasing after a giant laser beam; a scientist being eaten by a venus fly trap, a star falling through a Christmas tree as a scientist tries and fails to put it on top, a scientist going to a 'moonshine' bar, robots attending a seminar, a scientist trapping a human brain in a forcefield, and scientists stepping through portals. In the sky above the spaceship, Santa is being abducted by aliens.
