Eleanor grows up with a disaster prepared grandfather, doing drills and eat MREs. She mostly doesn't want to do it any more, until she discovers a website that says the world is going to end due to an asteroid hitting Earth. Although most adults are skeptical, Eleanor believes, and she and some fellow students at school start a club to prepare for the end of days. It was heartbreaking to watch Eleanor believe something that adults found skeptical, but I also found it useful as a way to look at how people can get stuck believing something incorrect and how hard it is to let go.
