Nina loves her small family and is passionate about her job as an architect. When she returns to work after parental leave, she is able to save the office from bankruptcy with a brilliant idea. The only catch: She has to pretend to be a single person who is married to his job. Because the client, Lene, is a dragon and doesn't think much of working mothers at all. Nina doesn't get any help from her husband Torsten because he sees her dream job as a threat to the family. The police officer is currently completing his high school diploma. The fact that his wife is surpassing him in career matters and will soon be bringing home more money than him scares him. In times of need, Nina passes him off as her brother and secretly hires the rental grandma Irmgard (70). Between lies and success, Nina's life gains so much momentum that she soon can no longer find the emergency brake.
