Three mature women meet in group psychotherapy. Although they differ in profession and character, they have the same problem that they try to solve in psychotherapy. Their depression and suffering have a common denominator: the infidelity of a couple to whom they sacrificed dozens, often difficult, years of living together. It spontaneously brings them closer and they decide that revenge will be better than an expensive session with a psychotherapist. They will help each other with that. They will prepare a real hell on earth for their unfaithful husbands.
