<p>At the start of high school, Piper, Sophie, Isabella and Honor think they will be best friends forever, so they sink a time capsule in the lake with a list of things they want to do before graduation.

Sophie pledges to stay a virgin until she is married and has created a purity app. Isabella is the feminist femme fatale who's the editor of a zine. And Honor is the pride and joy of the munity. Her dream of being a professional ballerina is taking off. But when tragedy strikes, the former BFFs must reunite, break open the capsule and plete the pre-graduation bucket list.</p>
