Chad Keeler hates his father for abandoning him when he was a boy of 10. His father, Alonzo, has become a believer but doesn't know how to reach out to his son. To make matters worse, a group of gold-hungry thieves sets out to kill him for the treasure map that he determines to use as a peace offering with his son.

Wichita Slim is an ex-outlaw turned U.S. Marshal. His lightning draw is being used on the right side of the law—until the Dry Gulch Bank is robbed. Knocked unconscious during a shoot-out with the robbers, Slim loses his memory and is captured by his old outlaw gang. He rides along for a series of robberies but knows that something isn’t right. The Territorial Governor issues an ultimatum to Gospel Bill: “Bring Slim back—dead or alive.”

In this unforgettable, heart-warming, heart-pounding adventure, U.S. Marshals Bill Gunter and Wichita Slim hit the trail to track down the outlaws who have kidnapped Bill Gunter’s six-year-old nephew, Ty. Indians, outlaws, ambushes, and the plan of the enemy can’t stop the covenant these men have made with God, each other, and young Ty’s mom. Even the wicked Saul Gillespie plots to get the marshals before they get him.
