This is a rather interesting (and amusing) tale of a spaceship that goes to a planet to investigate a call for help, only to find there's seemingly nothing wrong. The people that live on the surface of the planet are party-animal types, and give the impression that all is well, but they seem to be hiding something, like, the fact that they imprisoned the real inhabitants of the planet to do slave labor in the mines underground.

The year is 1822, and the Mimbreno Apache Indians enter into an agreement with a Mexican mining company, relinquishing all mining rights and pledging the safety of the copper town of Santa Rita del Cobre. Unfortunately, American companies are also interested in the precious metal deposits, and the Apaches are ultimately massacred under their orders. On the eve of the Mexican-American war, Ulzana, a young Apache warrior, sets out to avenge the extermination of his tribe. (firstrunfeatures.com)
