All of Kansas was threatened by the invading swarms of warring Indians. No one was safe from the Dog Soldiers, a band of cruel warriors who tortured their victims to a slow death.

Another more treacherous force was driving the Indians to massacre and the Rio Kid had to shoot his way to the truth before the reign of blood took them all.
