The Lonesome Shooter

In the desolate plains of Wyoming, there lived an aged cowboy named Jack. His weathered face bore the marks of a life spent in hard work, and his heart held unwavering love for his only son, Ethan, who had left the ranch to serve in the US Army.
One day, a somber knock on his door shattered his tranquility. A military officer delivered the heart-wrenching news: Ethan had been killed in action. The old cowboy's world crumbled around him, his grief threatening to consume him. Days turned into nights as Jack mourned the loss of his beloved son. But a sense of unease lingered in his mind. Rumors had reached his ears that Ethan's death may not have been as straightforward as the official report claimed.
Jack embarked on a solitary investigation. With the help of a former buddy, he delved into the murky depths of the conflict, seeking answers that had been deliberately concealed. Their search led them to a remote outpost where Ethan had been stationed. As they pieced together fragments of information from reluctant soldiers, a chilling truth emerged. Ethan had not died in battle but had fallen victim to a satanic ritual, a sacrifice at the hands of his own comrades.
Jack vowed to expose the truth and bring justice to his son's memory. He then goes to his son's mission field with the motive of revenge.
