Small ranchers around Dodge City are having cattle rustled along with cowhands killed and wounded. Sheriff Bassett is sick and Deputy Tillman is out of town so it is left to Earp to handle the problem. The ranchers know the Butch Henry gang is responsible and they are holding cattle at Salt River Bend. Earp doesn't like using a posse so he has phony wanted posters printed by Mr. McCabe showing Earp and Bat being wanted men from Texas with different names. They go undercover to infiltrate the gang. It works as Bat knows Texas but Earp has little knowledge so Bat tries to bring him up to speed. Butch Henry has nineteen notches on his gun but Earp soon discovers Zach Newcomb is the real boss but no one likes him. When he challenges Earp's identity, Earp shoots him in both arms. Butch has decided to take the men into Dodge City to steal some quick money. Bat and Earp go along but when a posse unexpectedly appears they take cover and start a gun battle with the outlaws. Earp knocks out Butch with a grazing bullet along with some others as the posse arrives to finish the fight and take prisoners.
