High school freshmen Piper, Sophie, Isabella, and Honor, certain of lifelong friendship, bury a time capsule containing their pre-graduation aspirations. Years later, they've diverged dramatically. Piper's become the life-of-the-party, a carefree spirit; Sophie, a devout virgin, champions chastity via her own app; Isabella, a fiercely independent feminist, spearheads a zine; and Honor, a rising ballet star, embodies community pride. However, a devastating event forces this fractured quartet to reconcile, unearth their buried dreams, and confront their unfinished bucket list.
