As 16-year-old Charlotte works her way through school life with her friends, she realises that the world she once knew has been invaded by an infectious disease that is spreading all around the world so quickly that she has little time to think about what is actually going on. A serious wakeup call stuns her into adult mode and she and her friends fight for their lives. However, she gets distracted when she finds her crush to still be alive, and tells her his true feelings for her. Love, loss and emotional wreckage ... its just like living in the world before it was tipped up-side-down - except for the fact that people you used to know are trying to tear the skin from your bones.
