Captain John Boyd receives a promotion after defeating the enemy command in a battle of the Mexican-American War, but because the general realizes it was an act of cowardice that got him there, he is given a backhanded promotion to Fort Spencer, where he is third in command. The others at the fort are two Indians, George and his sister, Martha, who came with the place, Chaplain Toffler, Reich, the soldier; Cleaves, a drugged-up cook; and Knox, who is frequently drunk.
