It's Baia Sunday somewhere in the center of Athens and a mailbox full of letters is blown up by a group of kids. But what the three children don't realize is that their prank is going to trigger dramatic developments for some of the recipients. Like Andia who is waiting for certificates from Tirana in order to get a residence permit. Or Lena and Manu, a young couple who will have a bad fling if they don't get their hands on the LSD tabs they intend to smuggle. Or the elderly Thalia, who, returning from the church, cannot imagine that one of the letters burned in the middle of the street concerns her personally.
