The Dutch Henry gang is rustling cattle and killed ranch hands on some of the smaller ranches around Dodge City. Sheriff Bassett is sick and Deputy Tillman is gone so Earp and Bat decide to go undercover into the gang rather take a posse.

Gene sets out to capture his friend's killer, but when Sheriff Davis unwillingly cooperates in the search, Gene begins to suspect the lawman of being in cahoots with the outlaw.

Gene helps a rainmaker and several honest ranchers drive out land-swindlers and a drought.
