Rick and Morty regain consciousness to learn that they have been mind-controlled by face-hugging alien parasites called the Glorzo. Having no memories of their time as hosts, they strap the dead Glorzo to their faces and learn the Glorzo have created a sophisticated society. Believing they are attempting to use Rick's ship to power a superweapon that will spread them to Earth, the duo manage to fight their way off the Glorzo home asteroid, causing mass destruction along the way.
