After nineteen years, Captain Travis Butler wants to complete his cavalry service and retire, marry his lady love, Victoria, and settle on his ranch in Oklahoma, but at the request of General Gable, a man he deeply respects, Travis and his best friend, Sergeant Noah Stubborn, can’t muster out just yet.

Travis and Noah are ordered to track and capture, or kill, Black Patch, an Apache formerly enslaved by powerful Mexicans, who, along with his gang, is cutting a murderous, bloody path from Mexico to the United States. On this perilous journey, Travis and his team of soldiers, Navajo scouts, and one drunkard of a tracker, will face off with Black Patch, the Mexican Army, renegade Navajos, and a couple of backstabbers. Prepare to be swept away like in Westerns of old by The Last Assignment.
