Set in New Mexico, Sonora, Arizona and California in 1867. Jubal Quinn is a black trooper in the 10th Cavalry accused of murder. Doomed to hang, he escapes the stockade aided by Kiowa boy Billy Songbird.
Hot in pursuit, Lieutenant Sam McAlister’s devotion to duty becomes obsession. Not even a beautiful Mexican girl’s love can deter Sam until either he or Jubal is dead.
