Lance Kincaid struggles to discover his past after losing his memory due to wounds he received in a Civil War battle. His search takes him from Illinois to Bell County, Texas, by way of Fort Griffin. His trip is plagued by run-ins with red neck Yankees and Lipan Apaches. He is smitten with the fort commander's daughter, Amy Scott, but his romantic desires must be put on hold until he determines if he has family obligations.

Dark Moon, a Tonkawa Indian scout from Fort Griffin, guides him and his partner Hefty from Fort Griffin through the Comanche territory to reach Belton, Texas.

With the help of Dr. Barton and Judge Tayler, Lance locates his family ranch only to find the Union Regulators have confiscated the property. Still without any memory of his past, he must find those behind this skullduggery and try to recover the ranch. With only determination and skill with a gun, he sets out to bring the wrongdoers to justice. In the end he finds himself face to face with Slade Cannon, a hired killer. He regains his memory when he receives help from an unsuspected source only to find that total justice has not been served.
