This "Blut und Boden" film was actually produced in 1931 during the Weimar Republik years. Its theme of poverty-stricken farmers leading a revolution against forced land sales and big city finance 

auctions met no resonance by the established film distributors.     They were too busy sending notorious films on prostitution, heroin addicts, homosexuality, sexual diseases, and anti-war films into movie theaters.

The film was shot in  and around the then-East Prussian village of Lenzen, not to be confused with the present-day village today located outside of Berlin.

The film finally had its premiered on April 26, 1933 and was a film shown in Third Reich schools and categorised as a "Schulfilm."  The destitution and plight of  German farmers was championed seven months after this film's premiere, with the Ufa film Blut und Scholle, which was released under the title of Du sollst nicht begehren.  Neither film made it into the top 100 box office films that year.

Unter der schwarzen Sturmfahne's Director, Rolf von Sonjevski–Jamrowski,  made a short film for Walter Darré called Blut und Boden, and in 1936 the renowned feature–length documentary film, Der ewiger Wald.

The film's plot, as found on the Internet, reads:

For over 400 years since the Peasant Uprising, the Hartkopfs, the “Steel Farmers” have worked their own fields. Respected by everyone, Hermann Hartkopf, the owner of the farm, married a poor woman against the will of his father, because in doing so, he was the first in his family to have to take out a mortgage to pay off his siblings. Up to his final mortgage payment, he worked the land diligently, loyally supported by his woman, Annamarie, who did double duty in the home. They cleared the forest, tree by tree. But the price of wood dropped and it wasn’t enough. They worked the fields, bringing in the harvest with great effort. But that, too, made little difference. They had to harvest even more just to keep up with the amount needed to make a minimum sale. And when they finally met that quota and brought it to the city to seel, Siegfried Lebenberg, the master of all the farmers’ needs and wishes, didn’t want it, because every farmer wanted to pay their mortgage with grain. Lebenberg did indeed take the grain; but only at a very small exchange rate, for the price of grain was dropping daily. But, at least, it was enough to pay the final mortgage installment … if … yeah, if the farmer could have used it to pay off the mortgage! You see, his wife became even sicker … and this, right before the birth of the heir to the farm. But how was the farmer supposed to do his planting and harvesting now? And right before having to let his farmhand go right before the New Year?
