A family is brutally murdered and their homestead burnt to the ground. The bodies are so badly disfigured that identity is difficult to determine, but one of the daughters is known to be missing. Is it 18-year-old Grace Mayfield or her younger sister, Chrissy? The missing Mayfield girl must now be found and the killers brought to justice. Some say it was the work of renegade Cheyenne. Sheriff August "Gus" Ward has his doubts, but evidence is scant. When the mysterious shooting of a stock agent on the streets of Laramie is linked to those who may have been responsible, Gus is faced with the savage reality that justice might not be served unless he is willing to take matters into his own hands. If he does, is he still a man of the law, or has he crossed the line to become an executioner, and no better than those he is willing to kill?
