In the quaint little town of Ponyville, its inhabitants are slowly starting to forget the fact that one another exists. Friends turn into strangers, lovers into acquaintances, and nopony seems to notice. Nopony except for a small group of six that find themselves being drawn together by a single mailbox that mysteriously appears in the center of town. A lonely mailbox that is writing letters back to them, telling them all that their time is running thin. And if nothing is changed, Ponyville as they know and love will be lost forever.
