Badlands of Dakota (1941)

"Thundering Down from the Black Hills...Come the Boldest, Blackest Days of the West! Deadwood City -- a Roaring Capitol of an Empire of Lawlessness -- Where Life Was Cheap -- Love Priceless!"

In the Dakotas during the days of the Great Gold Boom, brothers Jim and Bob Holliday are bumping heads over the affections of pretty Anne Grayson. While all this is going on, Wild Bill Hickok does his best to neutralize the local criminal element-and to fend off the romantic overtures of boisterous Calamity Jane.
