Filmed in sumptuous black and white, and full of scenes of lush, strange beauty, it tells the story of Vittoria (Monica Vitti), a young woman who leaves her older lover (Francisco Rabal), then drifts into a relationship with a confident, ambitious young stockbroker (Alain Delon). Using the architecture of Rome as a backdrop, Antonioni achieves the apotheosis of his style in this return to the theme that preoccupied him the most: the difficulty of forming true connections amidst the meaninglessness of the modern world.
