In a working-class town, Anthony and Dylan, two inseparable 14-year-old teenagers decide to go on a walk for a retro house party in a nightclub called the Komplex. While one wants to join Océane, a young girl with whom he is in love, the other wants to escape from Joe, his brother's dealer, from whom he stole money and part of his stock.

They loved each other a long time, a long time ago. One is afraid he hasn't seen all this time go by. The other, of the time which has passed and which is to come. On the way to vacation, a strange accident will blow everything up.
