[citation needed] Diana is a Roman wife happily married to sympathetic Paolo, but she is keen on playing benign games of seduction with other men while resisting the advances of chic lingerie shop owner Silvio.

However, under the influence of her lesbian friend Antonietta and raunchy sister Nadia, Diana starts to move the ongoings further while Paolo is still prone to believing that events narrated by her are merely fantasies.

Nevertheless, when the French Sadean antiques dealer Donatien Alphonse leaves marks on her body, Paolo understands that Diana is cheating on him and throws her out of the house.

In a retrospective review, Sight & Sound reviewed both The Key (1983) and All Ladies Do It, noting that the latter "shows a marked decline in narrative sophistication and wit" noting that the Venice setting in this film is set more in studio-based constructs than The Key.
