Seeking to escape the notoriety of his past, Gain Carson rode away from the Kansas town where he had earned his fame twenty-five years ago. However, the aging lawman and gunfighter cannot ride away from his reputation or the fast gun that rests on his hip. When he receives an urgent telegram from Nora McDonald, a woman he formerly loved, Gain leaves Montana and heads southward. Along the way, he encounters Slaton Callfield, a young man with a mysterious past.

Together, the legendary gunman and this young stranger encounter raging rivers, treacherous horse thieves, and a homicidal preacher. They also cross the path of Deadwood’s own Calamity Jane. Armed with a blazing fast gun and a fierce desire to protect the woman he loves, Carson alone must confront his past and the deadly band of outlaws who are threatening the Kansas town of Wichita.
