The magnificent cow Senta has escaped from an LPG. Matuschek, a single farmer, joins the search. However, the valuable animal is not found and is believed to have strayed across the border into Poland. Meanwhile, Senta is in Matuschek's barn. His maid Mathilde and neighbor Dattelmann have captured her and brought her there. Matuschek conceals a letter to Poland because of the supposedly border-crossing cow and is embarrassed when the cattle farmer Franze Flohr discovers the cow in his barn. Nevertheless, Matuschek and Franze become a couple who also become closer to the LPG.
