Lisa Palmer finds herself the owner of Evergreen’s former post office, which has been sitting vacant for the past few years. In hopes of saving the historically magical place in town, she and the Evergreen cast of characters set out to restore it to its former glory. In the process, they find the town’s beloved “Mailbox to Santa” with a letter inside that never made it out (assuming to the North Pole). Placing the mailbox back in the center of town where it belongs, an old tradition is made new again and an unfulfilled wish comes true.
