Fraudulent machinations of her dental spouse, from whom she lives apart, overthrow the housewife Cleo Berger into ruin. Cleo has to vacate her house and suddenly stands with her three children Tim, Emma and Sophie without housing and money in front of nothing. But Cleo can not be beaten and moves now to her father, a retired archaeologist, to which she has a difficult relationship. While she works as a waitress and has her hands full smoothing the waves between her annoyed father and the lively children, Cleo falls madly in love with the sympathetic-helpful neighbor Jan.
