With the War Between the States ended and most of the Indian tribes of Texas on reservations, the rangers are assigned to domestic law enforcement - chasing killers, bank robbers, thieves, and border-jumping bandits in the hill country north of the Llano River. Andy Pickard and ranger Farley Brackett, a former Confederate soldier, are assigned to deliver prisoner Jayce Landon to the sheriff of a neighbouring county to stand trial for killing Ned Hopper. The seemingly simple assignment quickly becomes complicated: the Landon and Hopper families are in a blood feud, the Landons are gathering to free Jayce and the Hoppers are gathering to kill him.
