In 2003 Mr. Danler's high school class got an assignment to write letters to their future selves. Twenty years later they receive them in the mail. Upon opening them the students are shocked to find that their envelopes contain old secrets that threaten to expose the truth about the tragic death of one of their classmates—and when one letter leads a student, Miranda, to jump to her death, the small community is rocked to its core.
Stunned by what has happened and armed with a clue of her own, Miranda's best-friend Audrey decides to track down her former classmates to get to the bottom of Miranda's death. In doing so, she sets off a chain of events that could expose the truth not just about one untimely death but two.
