US Marshal David Crockett Hall and Texas Ranger John Barclay Armstrong have set out chasing men, each for their own reasons. When their paths converge in Kansas, they discover the men they were following separately have now joined together and are heading for a giant payday somewhere, but where, the two lawmen don't know.

This story is about camaraderie, friendship, hardship, and an unerring desire to complete their jobs at any and all costs.

Set against the background of the late 1870s, the story takes us across the Midwest, Southwest, and into Colorado, unfolding a tale of two strangers becoming friends.
