Journalist Dieter Lindemann believes he has found the perfect solution for everyday family and work life with his wife Esther and their two five-year-old twins and three-year-old daughter with the principle of a "50:50 split" of job, housework and childcare. Unfortunately, Dieter realizes too late that they have forgotten to plan for each other as a couple, have grown apart in the stress of everyday life and only see each other when they hand over the children. That's why he is blindsided when Esther confesses that she has fallen in love with her attractive Danish lawyer colleague Lars Knudsen.
