What if your town was sliding underwater and everyone was ordered to pack up and leave? How would you and your friends spend your last days together? While the adults plan for the future, box up their possessions, and find new places to live, Keeley Hewitt and her friends decide to go out with a bang. There are parties in abandoned houses. Canoe races down Main Street. The goal is to make the most of every minute they still have together. And for Keeley, that means taking one last shot at the boy she's loved forever.
