The topic appealed to the Texas-bred Vidor and he offered a dual vision of the antebellum South's response to the war among the white planter class, sentimentalizing their struggle and defeat. Here, the western "pioneer" plantation owners possess less of the anti-Northern fury that led to secession by their "Old South" counterparts. The scion of the estate, Duncan Bedford (Randolph Scott) initially refuses to join the Confederate army ("I don't believe Americans should fight Americans") but his sister Vallette Duncan (Margaret Sullavan) scorns his pacifism and singlehandedly diverts her slaves from rebellion. The white masters of the "Portobello" plantation in Mississippi emerge from the conflict content that North and South made equal sacrifices, and that a "New South" has emerged that is better off without its white aristocracy and slavery. With Portobello in ruins, Valette and Duncan submit to the virtues of hard work in a pastoral existence.
