Under a presidential order, regimental colonel Abraham Biggs must force him to lead a patrol to return long-imprisoned, terminally-ill Cheyenne chief Yellow Hawk and his four relatives from Fort Berringer, New Mexico, to their Montana native land, the Valley of the Bears, as a 'humanitarian gesture'. Blocker is about to retire in 1892 after a career of protecting Wild West pioneer families by fighting Indian 'savages' from various tribes. Biggs also assigns to the detail a young French-speaking recruit, Private DeJardin.

Blocker chooses the detail that will accompany him: his trusty old friend, First Sergeant Thomas Metz, long-time aide Corporal Woodson, and promising newcomer Lieutenant Kidder, fresh from West Point. Under threat of a court-martial and loss of his pension, Blocker reluctantly accepts, despite his own gory history with the chief, who was responsible for the death of several of his friends and comrades. On a directive from President Harrison, he is to escort dying Cheyenne war chief, Yellow Hawk, and four members of his family back to their tribal lands in Montana. He is then called to the office of Colonel Abraham Biggs, who informs him of his final orders before retirement. In Fort Berringer, New Mexico, Captain Joseph Blocker rounds up an escaping Apache family and brings them back to the fort. Only Rosalee manages to escape the attack by hiding in a small rock outcrop in the forest. In 1892, settler Rosalee Quaid and her family are attacked by a Comanche war group who kill and scalp her husband and also shoot and kill her three children.
