More than ten years after fighting for the Confederacy in the Civil War, lifelong friends McCall Mac Patton and Ron Sandy Sands left Clay County, Missouri behind for another life adventure of prospecting for gold in the Colorado Rockies. Fate and destiny intervened and placed an old enemy Union Redleg Captain John Merna, who with his loyal men still hate anyone that had fought for the defeated Confederacy, in the path of Mac and Sandy near Dighton, Kansas. After an ambush that left Sandy dead, Captain Merna, thinking that Mac had perished as well, took his men west towards the Colorado Rockies following a map taken off a dead Confederate officer showing the location of the famed Reynolds Treasure that had been buried somewhere in the region of South Park, Colorado. Seeking the treasure, Captain Merna and his men also butchered any former Confederate that crossed their trail. Mac Patton, while seeking revenge for those that had killed his best friend, rescued a young Irish girl named Keegan Doreen O'Rourke and her pup Hugo after her folks had also been murdered by Captain Merna and his men. Mac Patton’s mission had now changed; he had to get Keegan safe to her Aunt Risa in Blackhawk, Colorado before he could resume his trail of justice and retribution against the saber carrying Captain Merna.Follow Mac, Keegan, and Hugo as they encounter renegade Union Redlegs, hostile Indians, sickness, tornadoes, and high mountain passes as they travel The Keegan Trail across the plains of Kansas and Colorado to the far away Rocky Mountains.
