Created by bestselling author Martha Williamson, "Signed, Sealed, Delivered", follows a quirky quartet of civil servants in the Dead Letter Office of the US Postal System who transform themselves into an elite team of lost-mail detectives. Their determination to deliver the undeliverable takes them out of the post office into an unpredictable world where letters and packages from the past save lives, solve crimes, reunite old loves and change futures by arriving late but always miraculously on time. The intrepid bunch is led by the charming and handsome (but idiosyncratic) Oliver who still considers the stamped and mailed letter to be the gold standard of human communication. His hapless team of lost letter experts, free-spirited Rita and oddly-intuitive Norman, are thrown for a loop when a beautiful, no-nonsense technophile named Shane is mistakenly transferred to their inner sanctum. Shane inspires the lovable crew to step up in a risky and unorthodox way, beginning with a chance to clear the name of a wrongfully accused man and reconnect him with the love of his life.

With a duty to deliver every last letter before Christmas, the beloved quartet of post office detectives 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, the Postables are more surprised than anyone to discover they've been a part of more than one miracle on this Christmas Eve.
