Mia fulfills her role as a picture-perfect wife and mother of two perfectly. Even too perfectly: Florian, a wealthy dentist who is only ever thinking about his next tennis match, takes his wife's commitment all too much for granted. For their spoiled teenage daughter Sarah and little Leon, mom's all-round service is as normal as the luxurious house with pool. Even her mother-in-law Helga, a dreamy old 68-year-old who lives with the family, doesn't lift a finger in the household. At some point, Mia is at 180: no one recognizes her achievements. This changes when she surprises three burglars in the house next door and behaves so professionally that she is encouraged to attend special training for "older applicants" at the police station.
