Mister Breuer, an eager businessman, finds out - some day - that the prosperity of his own 'consulting' company might not be the only goal in life. Wow, what a story!
This film relies heavily on verbal jokes. You should have a sense of humor for the *dry sort of humor* germans are said to have. After about half of the film even the few funny elements get worn out (for example the running gag with Breuer's incredible mother).
Although i have no doubt that people like Breuer exist, i give the film 40% at best. There are simply too many lame scenes not really working (especially the plot around the wife of the manager Breuer fired and tries to 'buy' for a night afterwards).
Watch 'Allein unter Frauen' if you want to see something really funny!
