In the 1875 Dakota Territory, a peace treaty between the US and the Sioux Nation is disrupted by a gold rush, drawing settlers and prospectors into the Black Hills despite the treaty. Captain Webb Calhoun, a strict and experienced officer, is tasked with keeping the gold seekers out of Sioux lands, but he faces opposition from saloon owner Ira Jordan, who wants to encourage gold-digging on Indian lands. When a new commander, Lieutenant Colonel Lloyd Unger, takes over the fort, he is easily swayed by Jordan's lies about Sioux attacks on settlers and farmers, leading to a tragic conflict between the US Army and the Sioux Nation.
Oh! Susanna
The valiant cavalry squadron stands strong against the merciless onslaught of the Sioux tribe, protecting the defenseless settlers from danger.
