Based on a story by Elmer Harris, the above-average Columbia production Court Martial was set during the Civil War. Carrying secret orders from President Abraham Lincoln, Northern secret agent Jack Holt heads below the Mason-Dixon line in hopes of capturing gorgeous Confederate spy Betty Compson. Disguised as a "rebel," Holt is able to join Compson's band of guerilla raiders. He falls in love with the girl and saves her from death at every turn. She in turn saves him from her vengeful comrades when his true identity is revealed. For failing to turn Compson over to the Northern authorities as originally planned, Holt is court-martialed and sentenced to be shot, but Compson, in the tradition of Cigarette in Under Two Flags, sacrifices her own life to save the hero from execution.
