Original title: Ο ουρανοκατέβατος

The late Pericles gets permission from God to return to earth and help his family, who has gone astray after his death. Invisible to all but present everywhere, he is able to eavesdrop on what's going on: his youngest daughter lives it up with some Teddy boys, his eldest do not intend to marry her fiancé, his son has become a crook, and his wife a gambler.
