The Doctor and K9 stumbled as the TARDIS came to an abrupt halt. "That's strange," The Doctor exclaimed, "We should be on Gallifrey, but that would take longer to reach." He put on his brown fedora and left the TARDIS, Romana and K9 soon following. The Doctor gasped; fire was everywhere, people were screaming and plastic men were killing people. "These aren't people, K9," The Doctor whispered, as if the words were tabooed, "We are on Earth, 2019; these are genuine plastic dummies, the ones you see in shops; Earth is once again invaded by the Nestene Consciousness!"
The Doctor ran past many dummies other possessed plastic objects. K9 was shooting the Autons. These were hard to kill, for plastic isn't exactly a living creature. The Doctor was explaining this to K9. "Master," K9 said, "Items known as 'wheelie bins' are eating people and creating plastic replicas. These are hardest to stop."
"I know, my dear K9," The Doctor inquired, out of breath from all the running, "the only way to stop these plastic demons is to stop them at the source; the Nestene Consciousness is hiding most probably underground, like in a manhole or something like that. We need to throw in some Anti-Plastic to the whirling pool of alien plastic. I have some Anti-Plastic in the TARDIS; I can teleport it here with my Sonic Screwdriver." He pulled out his Sonic, and when he pressed a button it almost instantaneously, some Anti-Plastic appeared. "The teleportation can't really happen unless you do something the right way, K9," The Doctor explained, "and can only be used in dire situations, like if a planet is under attack and they have no means of defense." The Doctor ducked and jumped over dead bodies and cars and shots from the Autons. He reached a manhole, and he and K9 entered to destroy the Nestene Consciousness.
They had to be sly, careful and cautious; Autons were climbing out of manholes. The Doctor spotted a door guarded by four Autons. "There we are, K9," he whispered to the robotic dog, "I'll just short circuit the Autons with my Sonic, and I'll throw in the Anti-Plastic. You stay out here." The Doctor dived in front of the Autons and pressed a button on the screwdriver; they short circuited and slumped to the floor. The Doctor opened the door, but as he entered, he was restrained by two Autons. "Well, Doctor," the Nestene Consciousness laughed mockingly, "not the strong Time Lord now, huh?" A third Auton threw The Doctor's Anti-Plastic out of the room. The Nestene Consciousness continued talking; "My Autons will destroy the Earth, and I can create a new planet; one inhabited by many more beings like I! And there is nothing you could ever do to… what are doing, dog? No...No… NOOOOOO!" K9 came in with the Anti-Plastic and pushed it into the Nestene Consciousness. The Autons stopped working, and the Nestene Consciousness stopped being. "K9, you good, good dog!" The Doctor smiled as the Autons holding him fell to the floor, "if you were a living being, you would have so many jelly babies right now!"
The Doctor pulled a lever on the TARDIS, and they left Earth. "To Gallifrey now, K9," The Doctor grinned, his teeth glinting, "the Time Lords need to see me about something; The Master is up to no-good again!"
