Verity crashed through the sky in a shower of comets with a mission. But when she landed, she suffered memory loss so she had no idea why she wanted to go to this planet. A girl named Noelle finds herself severely hurt in a crater, broken and bloodied. Noelle takes her back to a secret shed in the woods to keep her safe from her toxic parents and goes there every so often after school to check up on Verity. Once Verity hears that the planet will be overheated in 50 years, she remembers why she wanted to come to Earth: to save the planet. Verity explains to Noelle that there is a very toxic substance that is causing a disruption on the planet, causing it to overheat. If Earth explodes, then the Milky Way will die and wither, and so will Verity's planet. Noelle decides to help her travel to the various power plants to see who is corrupting the Earth with this toxic substance, and recruits her friend, Mikey.
