The Constancy of Reason
Florence, early 1960s. Bruno aspires to be hired at a prestigious factory, but his Communist ideals — instilled by Millo, a father figure and family friend in love with Bruno's widowed mother Ivana — are an obstacle. His relationship with Lori, a beautiful and tormented young woman who has just returned from Milan, reshapes his convictions. Freely adapted from a minor novel by Vasco Pratolini.
