Five small wagon parties have been attacked and massacred in the past month, and Custer's Seventh Cavalry is assigned to investigate. The Kiowa are being blamed for the attacks, but Custer believes they are not responsible. Complicating his efforts to find the real culprits are a bitter woman survivor of one of the attacks who thinks he's just a glory seeker, and a major sent from Washington who was a witness for the prosecution in his earlier court-martial.
