Three former college chums, Goldie Hawn, Diane Keaton and Bette Midler now middle-aged wives, have been brought together by the death of one of their group, who committed suicide when her husband ditched her. As the plot develops it turns that each of their husbands is ditching them for a younger girl/woman. They form the "First Wives Club" to plot exquisite revenge against their philandering husbands. Look out for cameo guest appearances by Ivana Trump and Heather Locklear.
I think some women will relate to this because it is all about revenge on the males and a terrific movie to watch if you have just been dumped, broken up with someone, and would love to get back at your scum partners.
