Mathilde Kratzer owns the entertainment venue "Bei Mathilde" (At Mathilde's). Her roommate Max also has a financial stake in the establishment, but only as a silent partner, which is why he works either as Mathilde's servant or as the bouncer. He would love to rename the venue "Bei Max und Mathilde" (At Max and Mathilde's), but Mathilde would rather return his investment. Because she can't afford to do so, Max is in financial trouble and is being relentlessly pursued by the tax authorities.
