Several years ago, the dazzling and lucky Lucy, a friend of her younger sister, stole her husband, handsome Peter, from Rose. However, there is no harmony in the lives of both women. Rose is jealous and gave up on herself too early, although she remains attractive in her own way. Lucy cannot find herself in the role of a wife and mother, and she also suffers from a “second wife” complex. It seems to her that Peter has lost interest in her too. A corporate party turns the situation around. Finally, Rose can take revenge - she has evidence that Lucy is not faithful to her husband. Now the life of the heroines is filled with fear of exposure, vengeful triumph, repentance, sympathy and new hopes for happiness.
