Trau’ niemals deinem Chef (2010)

On his birthday of all days: Oskar Moedebeck, a long-serving sales manager, is demoted and put in front of a boss half his age. And this Raphael Bluhm also turns out to be the new neighbor with whom the staid Oskar had a run-in first thing in the morning. Oskar can't believe it, but Raphael is already making out with the single mother next door - Oskar's daughter!
