A bourgeois couple, like so many others. It is clear that after a few years of marriage a bit of boredom may come, and it is their case: especially boredom in bed. And so husband and wife give themselves some distraction: he in the office, she at home. Marcello, manager, adores Milly, a woman with aggressive traits and more or less fetish clothing, alternating - at random - with classic clothes like a perfect secretary. One day Marcello dares the unattainable: touch Milly. But the gesture only triggers the indignation - unexpected - of her. Fortunately, there are friends: Riccardo, a friendly Don Giovanni, accompanies Marcello in an outrageous place. which becomes the stable destination of both nights. At the same time, Magda, in the beautiful marital home, has her usual extramarital affairs. Marcello is still obsessed with the secretary, and one evening he introduces her to his favorite place. Here Milly launches into a disturbing performance. A few days later, she will be transferred to another office, and replaced by a secretary as devout as she is ungainly. The turning point is near: Magda finds out how and where her husband spends his evenings. He enters the room, unbeknownst to her husband, who is there: he provokes him and surprises him, dressed in the same skimpy dress as Milly. It takes very little because Marcello rediscovers the eros of his wife. At home the passion is reborn, with impetus.
