Love comes in many forms, as does death.
Georgia, the summer of 1864:General William Tecumseh Sherman commands a mighty Union army, tasked with delivering a knockout blow to the Confederacy by rendering the rich resources of Georgia unavailable to the rebellion. Relying on impeccable intelligence, he launches an all-out attack on the Confederate lines at Kennesaw Mountain — and is bloodily repulsed. To make matters worse, his most reliable scout, Captain Ambrose Bierce, is critically wounded, and Sherman's most reliable general is mysteriously killed under the cover of battle. Sherman is persuaded by Union Army nurse Teresa Duval that these are murderous attacks perpetrated by a saboteur in his army. She urges him to summon Major Alphonso Clay, General Grant's sinister troubleshooter. Sherman is unaware that Duval is a spy for Wall Street financier Jay Gould, and has her own agenda regarding Clay. Clay and his friend Lieutenant Jeremiah Lot find themselves accompanying Sherman's army on its march through Georgia, desperate to identify the traitorous murderer before he can strike again, and possibly allow the Confederacy to snatch a miraculous victory from the jaws of almost certain defeat.
