Overview:

Regina Steinberg, 40, considers herself a sacrificing wife and mother. Everyone else thinks she is an egocentric. Her husband loves her anyway - until there is a scandal. When Regina, the wealthy dentist, suspected that her husband, Dr. Julius Stemberger, has a relationship, she puts her friend Nora on him. While Regina is on a spa with her mother, Julius seeks Nora's closeness, and Nora does not permanently fend off his advances. Eventually Regina finds out what is going on behind her back and Nora feels that Regina is not a "fine lady" when it comes to her interests.
