Salento, Italy, June 1934: A coach stops in the main square of Lizzanello, a tight-knit village where everyone knows each other. A couple gets off: The man, Carlo, a child of the South, is happy to be back home after a long time away; the woman, Anna --- his wife --- is a stranger from the North. Carlo’s brother is there to meet them, and he and everyone else can’t help but notice that Anna is as beautiful as a Greek statue. But Anna is not like the other wives, and there aren’t many options for a woman with her sensibilities. So when she learns that the post office is hiring, she leaps at the opportunity. A female letter carrier? It is unthinkable! But Anna passes the postal exam and soon becomes the invisible thread connecting the town. Letters convey information and emotion, but for some in Lizzanello, they are too little and too late.
