Everything seems to be going according to plan for graduate engineer Oliver Berger. He has only just landed a lucrative contract for his employer when he is already entrusted with the next major project. He willingly puts up with constant trips abroad and working through weekends. Meanwhile, his wife Lena and his ten-year-old son Moritz wait for him at his apartment in Erfurt or at the weekend house. Berger has never worried that his marriage might suffer as a result of his job. So he is all the more stunned when Lena leaves him at the drop of a hat. Suddenly, Berger is a single father.
