Plot synopsis: 1780: When farmer Schmitzdorff in Wust, Brandenburg, is denied permission to marry his stepdaughter Sophie, he goes to Potsdam to obtain permission from the king himself. Because when he believes he is in the right, the proud man stubbornly insists on his opinion. But his stubbornness gets the better of him when he meets the dashing Wordelmann, Frederick II's personal grenadier, in an inn on the way. The latter sees the farmer as a welcome distraction from his otherwise dreary everyday life. Wordelmann tricks Schmitzdorff at his expense and pretends to be allowed to perform the wedding because of his military affiliation. And so the grenadier ends up organizing a wedding that isn't a wedding and takes the dastardly prank to the extreme until everyone involved has lost their laughter.
