With a duty to deliver every last letter before Christmas, the beloved quartet of post office detectives�Oliver, Shane, Rita and Norman�are working around the clock to redirect Santa�s mail just as Oliver runs into his former Sunday school teacher. When they receive an emotional last-minute plea not meant for Saint Nick, but instead written to God, they must delay their own travel plans to make sure one little girl doesn�t lose her Christmas joy�something Oliver and Shane are also struggling to find as they each face painful holiday memories. With a little guidance from a mysterious post office volunteer, Jordan, the Postables are more surprised than anyone to discover they’ve been a part of more than one miracle on this Christmas Eve.
