Career woman Dana Weber has been working as editor-in-chief of a glossy magazine for 15 years. Her unshakeable self-confidence suffers its first blow when her snooty boss throws her out the door for reasons of age. Because she has never put any money aside and her ex-lover Martin won't lend her any, Dana has to vacate her luxurious apartment. At her older sister Maria's birthday party, it is not easy for her to pretend that everything is as it always was. Widow Maria, on the other hand, who lives in the villa she inherited from her parents, is calm and collected. The practicing esotericist is relaxed about refurbishing old furniture and gets on brilliantly with her sonny-boy offspring Robert - until it turns out that he has been ripped off by a notorious real estate shark and has used his mother's villa as a guarantee.

Maria, Dana and Julie learn from their mother's diary that one of them has been adopted.

The sisters couldn't be more different: while journalist Dana is fighting tooth and nail for the position of editor-in-chief, her sister Julie has decided to forgive her husband Bertram for his affair and return to him. However, when the betrayed woman learns that the infidelity is harmless compared to what Bertram did to her in the past, Julie draws a line under it. In this turmoil, Maria reminds her two sisters of the urgently needed patent renewal for the baking powder that their mother once invented. But Dana and Julie don't have the nerve for that at the moment. Because in addition to all the back and forth, they have both found a new crush - who happens to be the same man! Only when Maria finds out why the charming pilot Claus is courting Dana and Julie at the same time do the three "golden girls" pull together again ...
