Und alles wegen Mama (1998)

Unemployed Franz Zucker has a meager income and can barely afford the bare necessities. Together with his son Benny, he hatches a devious plan to defraud the moneylender Johannsen out of 25,000 marks. But as soon as that problem is out of the way, another one crops up: not only do the commissioner and neighbor Konrad Kaminski become suspicious, but Franz’s wife, Hilda, would also very much like to know how her husband suddenly came into so much money. To keep up appearances, Franz and Benny Zucker set up a freight company.
