Widow Lührs only receives a meagre pension and is therefore reliant on supplementary income, so she plays commercial cards without permission! One day, farmer Henck from Schandeloh appears at her house, who wants to scare his bossy wife with the help of the cards. Wilhelmine Lührs hesitates, but ham, sausage and money finally persuade her to change her mind. She lays out the cards for Mrs. Henck just as her husband had wished. But the fraud is discovered and Mrs. Lührs has to appear before the public prosecutor. But even in court, the ludicrous Wilhelmine manages to use her wisdom to cleverly get out of the affair.
