After the America Civil War ends, important political and military figures gather in Washington D.C. Gunfighter Wild Bill Hickok (William Hart) retires to Dodge City where he hangs up his gun belt and takes over a card table. Local lawmen are unable to rid the town of lawless cowboys. Hickok's arch-enemy and gang leader Jack McQueen accuses Hickok of losing his nerve. Hickok visits General Custer and retrieves his sword, taking up his role once more as a fighter for what's right. He returns to Dodge City and enlists the help of friends Wyatt Earp, Calamity Jane, Bat Masterson, Doc Holliday, Charlie Bassett, Luke Short and Bill Tilghman to clean up the town. Hickok falls for the wife of George Hamilton (Carl Gerard). Pursued for his crimes, McQueen leaves town and gets away. Hickok follows him and tries to bring him to justice.
