en Cuevana 3. Isn't life beautiful? Isabella Jung - who everyone just calls Bella - is tempted to answer the question with a firm "No!", because her husband Martin is cheating on her with a younger colleague at his birthday party, which Bella has organized especially for him. And in front of the assembled friends and neighbors. Together with her 15-year-old daughter Lena, Bella quickly moves out of their home and into a hotel. She secretly waits for a remorseful apology from Martin, but this does not happen: instead, he confesses to her that it was not a misstep, but that he is serious about the "new girl", Valerie. At first Bella is completely devastated, but in the end she doesn't let it get her down and dares to make a fresh start in life.
