After being absent for ten years, young Clara’s father comes back home, takes his daughter with him – she lived for that time at an aunt – and settles in Scano Boa, a poor village of fishermen on the Po’s delta. The new arrivals stir the mistrust and the discontent of the inhabitants, that do not hesitate to set the blame on them of every mishaps, mainly of the non-arrival of the sturgeons, the valuable fish, on whose capture everyone pins one’s hope. A really rare and forgotten film, neglected by the history of cinema and by the dictionaries. Maybe it is not a masterpiece, but a work able to explain the intense relations existing, mainly in the two decades following World War Two, between the biggest Italian river and the inhabitants of the country it runs through. A complex relationship, made of hope and apprehension, of sense of belonging and desire of flight, as in all love stories.
