The film takes place over the course of a single night: the longest night of the year, between December 21 and 22 (the winter solstice), when the sun sets around 4:30 p.m. and rises the next day at 7:30 a.m. A long night in which the stories, destinies, anxieties, and dramas of a provincial town in the south (Potenza) intertwine, even if only briefly. Fifteen hours of uninterrupted darkness in which human destiny becomes exceptional, as the night causes the anchors of the day to be lost and four personal stories suddenly accelerate.
