A rich girl breaks with her fiancee, moons about a bit, has a brief affair with her mother's stockbrocker. That's it.
Every frame is so beautifully composed. Those verticals!
Monica Vitti is a prophesy of Lady Di. The gawky grace of a wading bird, the big hair, the tilt of the head.

The beauty saves it from being boring- by a hair's breadth.
