The Earth is not in good shape. Because of climate change, the Earth is dying. Literally. The Earth is a sentient being that was a gift from God. Lucifer Morningstar takes this opportunity to crawl out of Heaven. He has big plans to save the Earth and not all of them are good. With the help of his new friend Rose, he plans to take over the world. Of course, Heaven does not want that to happen. Or at least, not without a fight.
