On a sunny day, three women prepare to attend a social event, but everything changes when they receive a mysterious letter that alters the course of their lives. The note, sent by a mutual friend, announces that she has run away with one of their husbands. Intrigued and somewhat bewildered, each of them begins to question their relationship, recalling moments and decisions they have made over the years.
Martha, a devoted mother, struggles with her insecurities as she contemplates whether her husband truly loves her or if the stability of their home is just a facade.

As each of them reflects on her relationship, memories and hidden truths are unleashed, leading to an emotional climax that challenges the very essence of marriage and friendship. Amidst laughter and tears, the film delves into the dilemma of loyalty, doubt, and the power of love, driven by a clever script and memorable performances that have left a mark on classic cinema.
