Hildegard Reimund has three grown-up daughters and would like nothing more than some grandchildren to make the house feel alive once again. Consequently on her 60th birthday she comes up with a very unusual idea: she will give her beautiful mansion to whoever of her daughters has a child first. Her daughters are all indignant at this crazy idea, for they have quite different plans: Susanne, the youngest, is a midwife concentrating entirely on her profession - especially since her experiences with men so far have been very far from satisfactory. Anja, always full of energy, is planning to emigrate to Brazil with girlfriend Karin. And the eldest daughter, Regina and her husband Robert enjoy a life of luxury punctuated by sushi and designer clothes. Consequently the three sisters resolve that none of them will get pregnant. But things don’t quite turn out that way: Susanne falls in love with Frank, Anja and Karin have such a huge argument that Anja ends up in the arms of her sensitive next-door neighbor Sebastian, and Robert discovers that one of his big stock market deals has gone terribly wrong, so the mansion would come in very handy to service his debts. Suddenly all three sisters are, despite their initial reactions, involved in a furious competition.
