An ancestral city; through its delicious botanical garden and its branched canals, we observe the clues and traces of its ancient culture. Two couples of men and women, former lovers, meet again one year later. The yesterday's breath of youth is still perceptible in their conversations. Is it still possible for us to love? Does youth really have an end? Like the networks linking the old city, what type of ecological existence does their culture require? Written by Venice Film Festival
