Angelo Posto is the postmaster from above with the mission to deliver four letters. He shuttles back and forth in the seasons to locate the receiving parties. On his way, he meets a wanderer family which has lost maternal love, two expeditors obsessed with their dream mirage and two old genies embracing the big full moon. The letters Angelo delivers bring surprise and hope.
But he is sore about the way he has been treated. Worse still, he is getting desperate about delivering the last unnamed letter in the snowy winter...Yet, nobody answers. Angelo feels so tired now. What should he do?
