Morna Dabney is engaged to soldier Clay MacIvor in the days before the War Between the States. Morna's grandfather Big Sam Dabney founded their Mississippi plantation near Levington, which thrives in the Deep South, but he remains loyal to the Union, as does his son Hoab, Morna's father. As Mississippi secedes, Hoab plans to withdraw the area around his plantation and remain neutral, and he gains support from local newspaperman Keith Alexander. Keith falls in love with Morna, whose fiancé Clay has joined the Confederate Army. Clay plans to punish the would-be neutral citizens of Levington by raiding the area, but Morna, with the help of her grandfather's Choctaw friend Tishomingo, attempts to thwart the attack. Morna sacrifices greatly to protect her home and the man she really loves.
