Principal Gottlieb Taft's twin brother Gotthold Taft partakes in the most recent prank by faking his death and promising a large inheritance to the Mommsen-Gymnasium and the principal. Of course, the inheritance is tied to many embarrassing conditions.

Mommsen Gymnasium director Taft secretly places his nephew as a spy with the difficult class of Pepe Nietnagel. During the celebration for the 100th anniversary, a simulated fire forces the school to shut down for a week. The director's attempt to get a tough teacher assigned by the department of education results in the exact opposite because of Nietnagel's intervention.

Retired tax official Willi Winzig spends his retirement happily and contentedly in his home. However, this changes when his sister Heidelinde, her daughter and his father want to move in with him, and as Willi is a good-natured man, he takes them in, but because they have no money and his pension is not enough for all four of them, he has to take on a new job. He gets a job as a salesman for household appliances, but his good nature gets in the way again.

Pepe Nietnagel and his fellow students of the Mommsen school come up with all kinds of ideas to get out of doing any actual school work. This includes simulating suicides, setting off the air-raid sirens and abusing the school director's new broadcasting system. They succeed in sending their teacher to a sanatorium and get a replacement that turns out to not be so bad after all.

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.
