Questo nostro amore

January 1967. The Costa and Strano families survived in the same building in Turin. Vittorio Costa, already married to another woman, lives with Anna Ferraris. The couple, who has three daughters, fears that their situation, irregular for the time, is discovered. The Strano family, on the other hand, is a large family of Sicilian origin, composed of Salvatore, Teresa and their four sons. The two families approached a lot, given the love story of the firstborn.
